Kind Code:
A1
Abstract:
A polythiol composition containing polythiol compound A, which is 4-mercaptomethyl-1,8-dimercapto-3,6-dithiaoctane, and compound B1 which shows a retention time of 65-75 minutes in a high-performance liquid chromatography measurement under measurement condition A, wherein the peak area of compound B1 in the high-performance liquid chromatography measurement is 1.30 or less relative to the peak area of polythiol compound A of 100. Measurement condition A: Column: ODS-A. Mobile phase: a mixed solution of acetonitrile/aqueous 0.01 mol/L potassium dihydrogen phosphate solution = 60/40 (vol/vol). Measurement solution: a mixed solution of 160 mg of the polythiol composition and 10 mL of acetonitrile. Detector: a UV detector with a measurement wavelength of 230 nm. Column temperature: 40°C. Flow rate: 1.0 mL/min. Injection volume: 2 μL.
