Chemical Structure

5-Methoxy-6-(trifluoromethyl)pyridin-3-ol CAS 1256819-72-3 chemical structure

Description

CATO manufactures 5-Methoxy-6-(trifluoromethyl)pyridin-3-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.

CATO supplies 5-Methoxy-6-(trifluoromethyl)pyridin-3-ol (CAS 1256819-72-3), a certified reference material (molecular formula C7H6F3NO2, MW 193.12 g/mol) for analytical method development and quality control.

5-Methoxy-6-(trifluoromethyl)pyridin-3-ol (C7H6F3NO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, 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.

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.
