Scope
This document specifies the requirements, test methods, inspection rules, marking and accompanying documents, as well as packaging, transportation, and storage for the by-product sodium bromide of pharmaceutical intermediates. This document applies to sodium bromide aqueous solutions produced as a by-product of the production of nine pharmaceutical intermediates, including 1,2-cyclopentanedimethylide, 2,4,6-tribromoaniline, 4,4-dibromodiphenyl, 1-bromonaphthalene, 2-amino-benzophenone hydrochloride, 2-bromoethyl acetate, cyanide bromide, 2-bromoacetaldehyde dimethyl ether, and 2-bromoacetaldehyde diethyl ether. These solutions are obtained after recrystallization and drying processes and are mainly used in the chemical industry.
