Chemical Structure
Description
CATO supplies 4-(4-Methoxyphenyl)pyridin-2-ol (CAS 442682-57-7), a certified reference material (molecular formula C12H11NO2, MW 201.22 g/mol) for analytical method development and quality control.
The molecular framework of 4-(4-Methoxyphenyl)pyridin-2-ol (C12H11NO2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
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 4-(4-Methoxyphenyl)pyridin-2-ol 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.
