Chemical Structure
Description
As a certified reference material (CRM), 2,2'-((3-Chlorophenyl)methylene)bis(3-hydroxy-5,5-dimethylcyclohex-2-en-1-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.
2,2'-((3-Chlorophenyl)methylene)bis(3-hydroxy-5,5-dimethylcyclohex-2-en-1-one) (CAS 868273-24-9), molecular formula C23H27ClO4 and molecular weight 402.91 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution, 2,2'-((3-Chlorophenyl)methylene)bis(3-hydroxy-5,5-dimethylcyclohex-2-en-1-one) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 402.91 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
