Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 4,4'-(Cyclohexane-1,1-diyl)bis(2-cyclohexylphenol) (CAS 4221-68-5), a certified reference material (molecular formula C30H40O2, MW 432.64 g/mol) for analytical method development and quality control.
4,4'-(Cyclohexane-1,1-diyl)bis(2-cyclohexylphenol) (C30H40O2) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 4,4'-(Cyclohexane-1,1-diyl)bis(2-cyclohexylphenol) 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.
