Chemical Structure

[D-Ser8]-Semaglutide A CAS CATO-C4X-2226116 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including [D-Ser8]-Semaglutide A.

CATO supplies [D-Ser8]-Semaglutide A (CAS CATO-C4X-2226116), a certified reference material (molecular formula C187H291N45O59, MW 4113.58 g/mol) for analytical method development and quality control.

The molecular framework of [D-Ser8]-Semaglutide A (C187H291N45O59) is characterized by a nitrogen-containing heterocyclic scaffold, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), [D-Ser8]-Semaglutide A 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.
