Chemical Structure
Description
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.
6-Ethyl-2,2,4-trimethyl-1,2-dihydroquinoline-8-carboxylic acid (CAS 940980-94-9), molecular formula C15H19NO2 and molecular weight 245.32 g/mol, is a CATO reference standard with documented purity and traceability.
6-Ethyl-2,2,4-trimethyl-1,2-dihydroquinoline-8-carboxylic acid (C15H19NO2) contains a nitrogen-containing heterocyclic scaffold, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures 6-Ethyl-2,2,4-trimethyl-1,2-dihydroquinoline-8-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.
