Epalrestat CAS 82159-09-9 chemical structure

Description

As a certified reference material (CRM), Epalrestat 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.

Epalrestat (CAS 82159-09-9), molecular formula C15H13NO3S2 and molecular weight 319.40 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C15H13NO3S2, Epalrestat contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 319.40 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
