5-(3-Formylphenyl)-2-hydroxyisonicotinic acid CAS 1261945-51-0

Description

The occurrence of 5-(3-Formylphenyl)-2-hydroxyisonicotinic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 5-(3-Formylphenyl)-2-hydroxyisonicotinic acid (CAS 1261945-51-0), a certified reference material (molecular formula C13H9NO4, MW 243.21 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 5-(3-Formylphenyl)-2-hydroxyisonicotinic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 243.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 5-(3-Formylphenyl)-2-hydroxyisonicotinic 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.
