Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3,6,8-Trimethyl-2-(p-tolyl)quinoline-4-carboxylic acid.
CATO supplies 3,6,8-Trimethyl-2-(p-tolyl)quinoline-4-carboxylic acid (CAS 932886-85-6), a certified reference material (molecular formula C20H19NO2, MW 305.37 g/mol) for analytical method development and quality control.
3,6,8-Trimethyl-2-(p-tolyl)quinoline-4-carboxylic acid (C20H19NO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 3,6,8-Trimethyl-2-(p-tolyl)quinoline-4-carboxylic 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.
