Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2-Methoxy-6-(2-naphthalen-1-yl-ethyl)-benzoic acid methyl ester (CAS 1171921-51-9), a certified reference material (molecular formula C21H20O3, MW 320.38 g/mol) for analytical method development and quality control.
2-Methoxy-6-(2-naphthalen-1-yl-ethyl)-benzoic acid methyl ester (C21H20O3) contains a steroid core, 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.
As a certified reference material (CRM), 2-Methoxy-6-(2-naphthalen-1-yl-ethyl)-benzoic acid methyl ester 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.
