Chemical Structure

3-(4-Hydroxyphenyl)picolinic acid CAS 1258622-77-3 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.

3-(4-Hydroxyphenyl)picolinic acid (CAS 1258622-77-3), molecular formula C12H9NO3 and molecular weight 215.20 g/mol, is a CATO reference standard with documented purity and traceability.

3-(4-Hydroxyphenyl)picolinic acid (C12H9NO3) contains an amino-acid-derived structure, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
