As a certified reference material (CRM), 3-Hydroxy-4-methyl-8,9,10,11-tetrahydrocyclohepta[c]chromen-6(7H)-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-Hydroxy-4-methyl-8,9,10,11-tetrahydrocyclohepta[c]chromen-6(7H)-one (CAS 431983-60-7) is a high-purity analytical reference standard with the molecular formula C15H16O3 and a molecular weight of 244.29 g/mol.
3-Hydroxy-4-methyl-8,9,10,11-tetrahydrocyclohepta[c]chromen-6(7H)-one (C15H16O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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.
