[Spectrophotometric analysis of tetracycline hydrochloride in the presence of thiamine bromide and riboflavin].
Spectrophotometric determination of tetracycline hydrochloride concentrations in the presence of thiamine bromide and riboflavin at a light absorption wave length of 300 nm was shown possible. When the ratio of tetracycline hydrochloride and the total of thiamine bromide and riboflavin (w/w) was at least 10:1 the error of the method was less than 2 per cent. The procedure is useful in quality control of the dosage forms.
