Chemical Structure

Boc-Cys(SEt)-OH · DCHA CAS 25461-01-2 chemical structure

Description

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

Boc-Cys(SEt)-OH · DCHA (CAS 25461-01-2) is a high-purity analytical reference standard with the molecular formula C10H19NO4S2C12H23N and a molecular weight of 462.71 g/mol.

The molecular framework of Boc-Cys(SEt)-OH · DCHA (C10H19NO4S2C12H23N) is characterized by an amide group, a sulfone group, a carboxylic acid 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

As a certified reference material (CRM), Boc-Cys(SEt)-OH · DCHA 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.
