100-43-6 Usage

Purification Methods

6 2 . Purify the monomer by fractional distillation under a good vacuum and in a N2 atmosphere and store it in sealed ampoules under N2, and keep it in the dark at -20o. The picrate has m 175-176o. [UV: Coleman & Fuoss J Am Chem Soc 77 5472 1955, Overberger et al. J Polymer Sci 27 381 1958, Petro & Smyth J Am Chem Soc 79 6142 1957.] It is used for alkylating SH groups in peptides [Anderson & Friedman Can J Biochem 49 1042 1971, Cawins & Friedman Anal Biochem 35 489 1970]. [Beilstein 20 II 170, 20 III/IV 2887, 20/6 V 213.]
