Halogenated Esters & Acid Chlorides Supplier | Aure Chemical

Aure Chemical supports B2B sourcing of halogenated esters and acid chlorides as part of our structured range of organic intermediates. These specialty chemicals serve as versatile building blocks in organic synthesis, supporting pharmaceutical intermediate synthesis, agrochemical intermediate synthesis, fine chemical production, surfactant intermediates, and functional materials development.

Halogenated esters, including chloro esters and bromo esters, combine the reactivity of a halogenated alkyl chain with the stability and functionality of an ester group. Acid chlorides, particularly fatty acid chlorides such as palmitoyl chloride, stearoyl chloride, and oleoyl chloride, offer high reactivity for acylation-related specialty synthesis applications. As a professional B2B supplier and sourcing partner, Aure Chemical works with qualified production partners to support customer evaluation of these halogenated intermediates according to agreed specifications.

This application page forms part of our broader Halogenated Intermediates and Halide Derivatives product group. We support B2B sourcing with documentation coordination and export communication for qualified buyers.

What Are Halogenated Esters and Acid Chlorides?

Halogenated esters are organic intermediates that feature both an ester functional group and a halogen atom, usually chlorine or bromine, attached to an alkyl chain. Common examples include chloro esters such as Methyl 6-chlorohexanoate and Ethyl 6-chlorohexanoate, as well as bromo esters like Ethyl 5-bromovalerate and Ethyl 6-bromohexanoate. These molecules are valued for their dual functionality, allowing selective chain extension, functional group transformation, or further derivatization in controlled synthesis environments.

Acid chlorides are highly reactive carbonyl compounds widely evaluated as acylation intermediates. This category includes short-chain acid chlorides such as 4-Chlorobutyryl chloride and longer-chain fatty acid chlorides including Palmitoyl chloride, Stearoyl chloride, Oleoyl chloride, and branched variants such as Isopalmitic chloride. Their reactivity makes them suitable for introducing acyl groups in specialty organic synthesis and functional chemical applications.

Both product families are included in Aure Chemical’s halogenated intermediates portfolio. We focus on providing materials for customer evaluation according to agreed specifications, subject to availability and project evaluation.

Product Range

Chloro Ester Intermediates

Chloro esters represent an important subgroup within halogenated esters. Products such as Methyl 6-chlorohexanoate, Ethyl 6-chlorohexanoate, Ethyl 7-chloroheptanoate, and Ethyl 8-chlorooctanoate are frequently evaluated in specialty organic synthesis projects.

These chloro ester intermediates provide a stable ester functionality combined with a terminal chlorine atom, supporting controlled chain-extension reactions and functional group transformations. Procurement managers often request these materials when developing intermediates for fine chemical or materials science applications. Aure Chemical supports sourcing of these chloro esters subject to availability and project evaluation, with COA, SDS, and specification documents provided where available.

Bromo Ester Intermediates

Bromo esters are often selected when higher leaving-group reactivity is required compared with certain chloro analogues. Key products in this category include Ethyl 5-bromovalerate, Ethyl 6-bromohexanoate, and Ethyl 7-bromoheptanoate.

These bromo ester intermediates may be considered for pharmaceutical and fine chemical intermediate synthesis projects, as well as agrochemical intermediate development, depending on the customer’s specific process requirements and regulatory evaluation. Their reactivity profile makes them suitable candidates for targeted alkylation or substitution steps in complex multi-step syntheses.

Acid Chlorides and Fatty Acid Chlorides

Acid chlorides serve as powerful acylation intermediates in specialty synthesis. 4-Chlorobutyryl chloride is a short-chain example that combines an acid chloride group with a terminal chlorine atom, offering dual reactivity for certain synthetic routes.

Fatty acid chlorides such as Palmitoyl chloride, Stearoyl chloride, Oleoyl chloride, and the branched Isopalmitic chloride are widely evaluated for surfactant, additive, and functional chemical intermediate applications. These long-chain acid chlorides are particularly useful in projects requiring the introduction of hydrophobic acyl groups.

Final suitability for any specific application depends on customer specifications and regulatory evaluation.

Typical Applications in Specialty Synthesis

Halogenated esters and acid chlorides are used across multiple sectors as intermediates. Typical application directions include:

• Pharmaceutical intermediate synthesis, subject to customer process route, purity requirements, and regulatory evaluation

• Agrochemical intermediate synthesis

• Specialty organic synthesis

• Fine chemical production

• Surfactant intermediate synthesis

• Functional additive intermediates

• Material and polymer-related intermediates

• Project-based sourcing and custom procurement for industrial R&D

These products may be used as intermediates depending on the customer’s process route, purity requirements, and regulatory evaluation.

How to Select a Suitable Halogenated Ester or Acid Chloride

International procurement teams and R&D sourcing specialists should consider the following factors when selecting halogenated esters or acid chlorides:

• Confirm the exact CAS number and product name to ensure the correct halogenated ester or acid chloride is specified

• Verify required purity, assay, and key impurity limits according to your process needs

• Determine whether a chloro ester, bromo ester, or acid chloride functionality best matches the required reactivity profile

• Assess any moisture sensitivity or handling considerations for acid chlorides

• Define target quantity and anticipated annual demand

• Specify destination country and port of entry

• Indicate preferred packing options

• Confirm whether dangerous goods classification or special export documentation will apply

Aure Chemical supports clear communication on these points to facilitate accurate quotations and efficient supply chain coordination.

Documentation, Packing and Export Support

Aure Chemical can provide available documentation such as COA, SDS, and specification sheets for customer evaluation. Commercial documents including commercial invoice, packing list, and standard export paperwork are prepared as part of our export coordination service.

Packing and shipping options depend on product properties, quantity, and destination. Sample requests are reviewed on a case-by-case basis depending on the specific product, quantity, destination, and regulatory feasibility. Batch availability, lead time, final specification, packing, and shipping method should be confirmed according to the product, order quantity, and destination country.

As a B2B sourcing partner, we focus on supporting international buyers with documentation coordination and clear export communication.
