4-Oxo Valsartan Benzyl Ester CAS 188240-32-6 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.

4-Oxo Valsartan Benzyl Ester (CAS 188240-32-6) is a high-purity analytical reference standard with the molecular formula C31H33N5O4 and a molecular weight of 539.62 g/mol.

4-Oxo Valsartan Benzyl Ester (C31H33N5O4) contains a nitrogen-containing heterocyclic scaffold, an amide 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).

As a certified reference material (CRM), 4-Oxo Valsartan Benzyl Ester 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.
