Chemical Structure
Description
As a certified reference material (CRM), 1,2-dihydrobenzo[k]tetraphene-1,2-diol 7456-87-3 KST-1B8312 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.
CATO supplies 1,2-dihydrobenzo[k]tetraphene-1,2-diol 7456-87-3 KST-1B8312 (CAS 7456-87-3), a certified reference material (molecular formula C22H16O2, MW 312.36 g/mol) for analytical method development and quality control.
1,2-dihydrobenzo[k]tetraphene-1,2-diol 7456-87-3 KST-1B8312 (C22H16O2) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
