3-Hydroxy-2,6,8-trimethylquinoline-4-carboxylic acid CAS 40445-40-7

Description

The occurrence of 3-Hydroxy-2,6,8-trimethylquinoline-4-carboxylic 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.

3-Hydroxy-2,6,8-trimethylquinoline-4-carboxylic acid (CAS 40445-40-7), molecular formula C13H13NO3 and molecular weight 231.25 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3-Hydroxy-2,6,8-trimethylquinoline-4-carboxylic acid (C13H13NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 231.25 g/mol, it falls into the medium-molecular-weight range. 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-Hydroxy-2,6,8-trimethylquinoline-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.
