Acetaldehyde 99% Pure Industrial Grade
Acetaldehyde (ethanal, CAS 75-07-0) is a colorless volatile liquid with a pungent fruity odor, classified under HTS 2912.12.00.00 as a separate chemically defined acyclic aldehyde without other oxygen functions. It serves as a key intermediate in producing acetic acid, pyridine derivatives, and synthetic resins.
Acetaldehyde Stabilized with Hydroquinone
Stabilized acetaldehyde contains a small amount of hydroquinone to prevent polymerization during storage and transport, remaining classified under HTS 2912.12.00.00 as the pure acyclic aldehyde per Chapter 29 note (f). Used primarily in pharmaceutical synthesis and as a flavoring precursor.
Paraldehyde USP Grade Acetaldehyde Trimer
Paraldehyde is the cyclic trimer of acetaldehyde, but pure monomeric acetaldehyde sources are classified under HTS 2912.12.00.00 as acyclic aldehydes without other oxygen functions. This USP grade is used in pharmaceutical formulations as a sedative-hypnotic.
Acetaldehyde Anhydrous Technical Grade
Anhydrous technical grade acetaldehyde is a high-purity form of ethanal without water content, directly classifiable under HTS 2912.12.00.00 as a separate acyclic aldehyde. Primarily used in the production of acetic anhydride and peracetic acid.
