Abstract
The raw material of cyclandelate was examined for preparation of the "Cyclandelate Reference Standard". Analytical data obtained were as follows: melting point, 60 degrees C; ultraviolet spectrum, lambda max = 252, 258 and 264 nm E1%1cm = 6.1 (252 nm), 7.5 (258 nm), 5.9 (264 nm); infrared spectrum, 3454, 2948, 1730, 1453, 1202, 737, 695 cm-1; thin-layer chromatography, no impurities were detected until 1000 micrograms; high-performance liquid chromatography (HPLC), one impurity was detected, loss on drying, 0.00%. Based on the above results, this raw material was authorized to be the Reference Standard of the National Institute of Hygienic Sciences.
