A gas chromatographic procedure has been developed for the determination of chlorobutanol in a variety of pharmaceutical preparations. Numerous columns were investigated and found useful. Chlorobutanol was separated from its degradation products o n all of these columns. Analysis of synthetic mixtur

Abstract
The antibiotic streptomycin can be reliably quantitated in injectable pharmaceuticals by GC. The manipulations are not difficult, and total analysis time for duplicate samples is less than twenty minutes.
Reaction of the drug with aqueous sodium hydroxide solution generates maltol, which is extracted into chloroform prior to silylation. The silyl ether of maltol is then assayed, using naphthalene as internal standard. Duplicate analyses of twenty pharmaceutical samples showed a relative standard deviation of Β±1.3%.
