Chemical Structure
Description
2-[3-(2-Chloro-phenyl)-propyl]-6-methoxy-benzoic acid methyl ester (CAS 1171923-84-4), molecular formula C18H19ClO3 and molecular weight 318.79 g/mol, is a CATO reference standard with documented purity and traceability.
2-[3-(2-Chloro-phenyl)-propyl]-6-methoxy-benzoic acid methyl ester (C18H19ClO3) contains a steroid core, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 2-[3-(2-Chloro-phenyl)-propyl]-6-methoxy-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.
