Chemical Structure

L-Selenocystine CAS 29621-88-3 chemical structure

Description

The molecular framework of L-Selenocystine (C6H12N2O4Se2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

CATO supplies L-Selenocystine (CAS 29621-88-3), a certified reference material (molecular formula C6H12N2O4Se2, MW 334.09 g/mol) for analytical method development and quality control.
