The occurrence of 2-(4-Chlorobenzyl)-6-methoxy-3,4-dihydronaphthalen-1(2H)-one is closely related to a steroid core, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(4-Chlorobenzyl)-6-methoxy-3,4-dihydronaphthalen-1(2H)-one (CAS 62085-82-9), molecular formula C18H17ClO2 and molecular weight 300.78 g/mol, is a CATO reference standard with documented purity and traceability.
2-(4-Chlorobenzyl)-6-methoxy-3,4-dihydronaphthalen-1(2H)-one (C18H17ClO2) 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.
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.
As a certified reference material (CRM), 2-(4-Chlorobenzyl)-6-methoxy-3,4-dihydronaphthalen-1(2H)-one 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.
