Chemical Structure
Description
As a certified reference material (CRM), 3-(Benzyloxy)-4-methyl-6H-benzo[c]chromen-6-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.
3-(Benzyloxy)-4-methyl-6H-benzo[c]chromen-6-one (CAS 302551-60-6) is a high-purity analytical reference standard with the molecular formula C21H16O3 and a molecular weight of 316.35 g/mol.
3-(Benzyloxy)-4-methyl-6H-benzo[c]chromen-6-one (C21H16O3) 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.
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.
