Determination of isoniazid in pharmaceutical preparations by reaction with radiochloramine-B.


PMID 2490531

Abstract

A method has been developed for the determination of isoniazid (INH) at microgram level in pharmaceutical preparations based on the oxidation of isoniazid by radiochloramine-B. Interference of vitamin C has been overcome by precipitation as lead ascorbate and that of rifampicin and p-aminosalicylic acid by selective extraction. Amounts as low as 25 micrograms of INH can be determined.
