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 6-Methyl-2-oxo-1,2,3,4-tetrahydroquinoline-4-carboxylic acid.
6-Methyl-2-oxo-1,2,3,4-tetrahydroquinoline-4-carboxylic acid (CAS 855165-89-8) is a high-purity analytical reference standard with the molecular formula C11H11NO3 and a molecular weight of 205.21 g/mol.
The molecular framework of 6-Methyl-2-oxo-1,2,3,4-tetrahydroquinoline-4-carboxylic acid (C11H11NO3) 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 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 6-Methyl-2-oxo-1,2,3,4-tetrahydroquinoline-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.
