Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 238.28 g/mol gives 2'-Hydroxy -5'- methyl chalcone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2'-Hydroxy -5'- methyl chalcone (CAS 1775-98-0), molecular formula C16H14O2 and molecular weight 238.28 g/mol, is a CATO reference standard with documented purity and traceability.
2'-Hydroxy -5'- methyl chalcone (C16H14O2) 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.
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'-Hydroxy -5'- methyl chalcone 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.
