Description
As a certified reference material (CRM), 6-(tert-Butyl)-4-hydroxycoumarin 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 6-(tert-Butyl)-4-hydroxycoumarin (CAS 186255-65-2), a certified reference material (molecular formula C13H14O3, MW 218.25 g/mol) for analytical method development and quality control.
Based on its molecular formula C13H14O3, 6-(tert-Butyl)-4-hydroxycoumarin contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 218.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
