Chemical Structure
Description
(S)-(+)-Repaglinide-d5 (ethoxy-d5) (CAS 1217709-85-7) is a high-purity analytical reference standard with the molecular formula C27H31D5N2O4 and a molecular weight of 457.62 g/mol.
Owing to deuterium isotope labeling, a steroid core, an amide group, a hydroxyl group, an ether linkage, (S)-(+)-Repaglinide-d5 (ethoxy-d5) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 457.62 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), (S)-(+)-Repaglinide-d5 (ethoxy-d5) 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.
