Description

Oxalyl Chloride is a highly reactive and versatile acid chloride reagent essential for organic synthesis. Its primary value lies in its ability to efficiently introduce the oxalyl group or act as a powerful chlorinating and dehydrating agent, enabling the production of key intermediates. This compound is critically needed by manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries for applications ranging from active pharmaceutical ingredient (API) synthesis to polymer modification.

Application

• Pharmaceutical Intermediate Synthesis: Key reagent for preparing acid chlorides, amides, and esters; used in the production of various APIs and fine chemicals.
• Agrochemical Manufacturing: Employed in the synthesis of herbicides, fungicides, and other crop protection agents.
• Peptide Coupling Reagent: Used in peptide synthesis, often in combination with dimethylformamide (DMF) as a coupling agent.
• Dye and Pigment Production: Serves as an intermediate in the manufacture of certain organic dyes and colorants.
• Polymer Chemistry: Acts as a modifying agent or cross-linking intermediate for specialty polymers and resins.
• Laboratory Research & Development: A fundamental reagent for organic transformations, including Friedel-Crafts acylations and the synthesis of heterocyclic compounds.

Quality Control

Our Oxalyl Chloride is manufactured under stringent quality control protocols to ensure batch-to-batch consistency and high purity suitable for demanding industrial applications. We adhere to relevant industry standards, and a comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee product integrity and support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat, moisture, and incompatible materials such as strong bases, alcohols, and amines. Due to its highly volatile and reactive nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen) to maintain purity and prevent hydrolysis.
