title: [Chlormadinone Acetate Reference Standard (Control 881) of National Institute of Hygienic Sciences].
abstract: Chlormadinone acetate was tested for the preparation of the "Chlormadinone Acetate Reference Standard (Control 881)". Analytical data obtained were as follows: loss on drying, 0.00%; infrared spectrum, 1740, 1715, 1658, 1604, 1587, 1256, 1244 cm-1; ultraviolet spectrum, lambda max = 284 nm; absorbance, E1cm1% (284 nm) = 539-549; optical rotation, [alpha]D20: -12.1 degrees; melting point, 214.6 degrees C; thin-layer chromatography, contaminants were not detected until 300 micrograms; high-performance liquid chromatography, one contaminant was detected. On the basis of the above results, this material was authorized as the National Institute of Hygienic Sciences Reference Standard (Control 881).
