Chemical Structure

L-Cystine-13C6,15N2 CAS 1252803-65-8 chemical structure

Description

CATO supplies L-Cystine-13C6,15N2 (CAS 1252803-65-8), a certified reference material (molecular formula [13C]6H12[15N]2O4S2, MW 248.24 g/mol) for analytical method development and quality control.

The molecular framework of L-Cystine-13C6,15N2 ([13C]6H12[15N]2O4S2) is characterized by a sulfone group. 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), L-Cystine-13C6,15N2 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.
