DL-Cystathionine CAS 535-34-2 chemical structure

Description

As a certified reference material (CRM), DL-Cystathionine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

DL-Cystathionine (CAS 535-34-2), molecular formula C7H14N2O4S and molecular weight 222.26 g/mol, is a CATO reference standard with documented purity and traceability.

DL-Cystathionine (C7H14N2O4S) contains an amide group, a sulfone group, a carboxylic acid 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
