title: [Triamcinolone Acetonide Reference Standard (Control 981) of National Institute of Health Sciences].
abstract: The raw material of triamcinolone acetonide was examined for preparation of the "Triamcinolone Acetonide Reference Standard (Control 981)". The analytical data obtained were: melting point, 289 degrees C (decomposition); UV spectrum, lambda max of 238 nm; IR spectrum, same as that of the Triamcinolone Acetonide Reference Standard (Control 834); optical rotation, [alpha]D20 = +106.8 degrees; thin-layer chromatography, no impurities detected; high-performance liquid chromatography, total amount of impurities less than 0.4%; loss on drying, 1.3%; assay by HPLC, 100.1%. Based on the above results, the raw material was authorized as the Triamcinolone Acetonide Reference Standard (Control 981) of the National Institute of Health Sciences.
