title: Analysis of steroid phosphates by high-pressure liquid chromatography: betamethasone sodium phosphate.
abstract: A sensitive, automatable high-pressure liquid chromatographic procedure is presented for the determination of steroid phosphates. Quantitation is described for betamethasone sodium phosphate in dosage forms in the presence of polar excipients. The separation of a multicomponent mixture of steroid phsophates also is reported.
