Product Description
Product name: Acetyl Chloride
Molecular formula: C₂H₃ClO
Acetyl Chloride, CAS 75-36-5, is a reactive acyl chloride used in acetylation and organic synthesis.

Acetyl chloride is not chloroacetyl chloride; they are distinct substances with different CAS numbers. Before an RFQ, confirm the intended acylation route, material compatibility, offered form, and current safety controls. Follow the current SDS for the exact offered form and the receiving site’s controls.
FAQ - Technical & Supply Chain
-
Q:
Are Acetyl Chloride and Acetic Chloride the same substance?
A: Yes. Acetyl Chloride and Acetic Chloride are names used for CAS 75-36-5, formula C₂H₃ClO. Do not confuse it with chloroacetyl chloride, CAS 79-04-9, which has a chlorine substituent on the carbon chain and is a different reagent. Purchase documents should carry the full name and CAS number. -
Q:
Which batch controls matter for Acetyl Chloride?
A: Agree GC assay and the treatment of acetic acid, acetic anhydride and other process-related impurities, plus color, density and water where the method is suitable. Because hydrolysis raises acidity and reduces usable acetylating value, review the batch COA together with the sampling method and container history. -
Q:
How should bulk Acetyl Chloride packaging and transfer be specified?
A: Use a dry, compatible, tightly closed container and transfer system approved for a corrosive, flammable and water-reactive liquid. Specify drum, isotank or other format, valve and gasket materials, inert-gas condition, seal arrangement and unloading connection. The receiving site should approve the current SDS and emergency controls before dispatch.
