Acetic Anhydride in Bulk

Acetic anhydride is the standard acetylating agent of the pharmaceutical and cellulose industries, used to make aspirin, paracetamol and cellulose acetate among many other products. It is also a listed narcotics precursor, which means every consignment is tracked and supply is restricted to buyers holding the correct licences. BulkFineChem supplies it strictly within that framework to licensed manufacturers across India.

FAQs

Questions buyers commonly ask about acetic anhydride.

• Do I need a licence? Yes. It is a listed precursor and we cannot supply without valid NDPS licensing.
• Is pharmacopoeial grade available? Yes, against IP or BP specification on request.
• Why must it be kept dry? It hydrolyses exothermically to acetic acid, degrading assay and creating a hazard.
• Can I get a sample? Only under the same licensing and documentation requirements.
• What documents are provided? GST invoice, batch CoA, SDS, TREM card and statutory precursor records.
