NOVEL THIOL COMPOUND, AND COMPOSITION FOR OPTICAL MATERIALS WHICH USES SAME

摘要

According to the present invention, it is possible to provide a thiol compound represented by formula (1):
wherein R 1 and R 2 each independently represent hydrogen or CH 2 SCH 2 CH 2 SH, and R 1 and R 2 are not the same. In addition, according to the present invention, it is possible to provide a mixture of the thiol compound and 4-mercaptomethyl-1,8-dimercapto-3,6-dithiaoctane, wherein the ratio of the thiol compound is 0.001 to 5.0% by mass.
