Chemical Structure
Description
The occurrence of 3593AE 438216-68-3 6-Methyl-2-(3-methylphenyl)quinoline-4-carboxylic acid C18H15NO2 is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3593AE 438216-68-3 6-Methyl-2-(3-methylphenyl)quinoline-4-carboxylic acid C18H15NO2 (CAS 438216-68-3), a certified reference material (molecular formula C18H15NO2, MW 277.32 g/mol) for analytical method development and quality control.
3593AE 438216-68-3 6-Methyl-2-(3-methylphenyl)quinoline-4-carboxylic acid C18H15NO2 (C18H15NO2) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3593AE 438216-68-3 6-Methyl-2-(3-methylphenyl)quinoline-4-carboxylic acid C18H15NO2 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
