Choline Aspirin Salt from Japan
Choline Aspirin Salt is the choline salt of O-acetylsalicylic acid, a bioavailable form used in oral liquid analgesics. Under Chapter 29 Note 5(C)(2), salts of organic bases with organic acids are classified with the acid or base occurring last in numerical order; choline (a quaternary ammonium base, heading 29.23) precedes O-acetylsalicylic acid (heading 29.18), so the salt is classified under 2918.22.00. It is a bulk chemical for pharmaceutical compounding.
