[Betamethasone valerate reference standard (Control 941) of the National Institute of Health Sciences].
The raw material for betamethasone valerate was tested for preparation of the "Betamethasone Valerate Reference Standard (Control 941)". Analytical data obtained were as follows: melting point, 194.3 degrees C (decomposition); UV and infrared spectra, the same as those for JP Betamethasone Valerate Reference Standard (Control 844); optical rotation, [alpha]20D = +79.4 degrees; thin-layer chromatography and high-performance liquid chromatography (HPLC), no impurities were detected; assay, 100.0% by HPLC. Based on the above results, the candidate material was authorized as the JP Betamethasone Valerate Reference Standard (Control 941).
