2-Hydroxy-6-(p-tolyl)nicotinic acid CAS 147269-18-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 229.23 g/mol gives 2-Hydroxy-6-(p-tolyl)nicotinic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Hydroxy-6-(p-tolyl)nicotinic acid (CAS 147269-18-9) is a high-purity analytical reference standard with the molecular formula C13H11NO3 and a molecular weight of 229.23 g/mol.

2-Hydroxy-6-(p-tolyl)nicotinic acid (C13H11NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, 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).

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.

CATO manufactures 2-Hydroxy-6-(p-tolyl)nicotinic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
