2-Hydroxy-5-(4-(pyrrolidin-1-ylsulfonyl)phenyl)nicotinic acid CAS 1262004-71-6 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Hydroxy-5-(4-(pyrrolidin-1-ylsulfonyl)phenyl)nicotinic acid.

2-Hydroxy-5-(4-(pyrrolidin-1-ylsulfonyl)phenyl)nicotinic acid (CAS 1262004-71-6) is a high-purity analytical reference standard with the molecular formula C16H16N2O5S and a molecular weight of 348.37 g/mol.

The molecular framework of 2-Hydroxy-5-(4-(pyrrolidin-1-ylsulfonyl)phenyl)nicotinic acid (C16H16N2O5S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 2-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.
