Chemical Structure

L-Homocystine-3,3,3′,3′,4,4,4′,4′-d8 CAS 182755-41-5 chemical structure

Description

The occurrence of L-Homocystine-3,3,3′,3′,4,4,4′,4′-d8 is closely related to deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies L-Homocystine-3,3,3′,3′,4,4,4′,4′-d8 (CAS 182755-41-5), a certified reference material (molecular formula C8H8D8N2O4S2, MW 276.40 g/mol) for analytical method development and quality control.

L-Homocystine-3,3,3′,3′,4,4,4′,4′-d8 (C8H8D8N2O4S2) contains deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
