6-Hydroxy-5-(4-(pyrrolidin-1-ylsulfonyl)phenyl)nicotinic acid CAS 1261978-04-4 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.

6-Hydroxy-5-(4-(pyrrolidin-1-ylsulfonyl)phenyl)nicotinic acid (CAS 1261978-04-4) is a high-purity analytical reference standard with the molecular formula C16H16N2O5S and a molecular weight of 348.37 g/mol.

6-Hydroxy-5-(4-(pyrrolidin-1-ylsulfonyl)phenyl)nicotinic acid (C16H16N2O5S) contains a flavonoid core, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

As a certified reference material (CRM), 6-Hydroxy-5-(4-(pyrrolidin-1-ylsulfonyl)phenyl)nicotinic acid 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.
