Chemical Structure
Description
endoD-Tyr(Et)2a-Atosiban (C54H80N12O14S2) contains 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).
endoD-Tyr(Et)2a-Atosiban (CAS CATO-C4X-229377) is a high-purity analytical reference standard with the molecular formula C54H80N12O14S2 and a molecular weight of 1185.42 g/mol.
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), endoD-Tyr(Et)2a-Atosiban 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.
