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 Diethyl (2,4-di-tert-butyl-3,6-dihydroxyphenyl)phosphonate (CAS 1420992-01-3), a certified reference material (molecular formula C18H31O5P, MW 358.41 g/mol) for analytical method development and quality control.
Based on its molecular formula C18H31O5P, Diethyl (2,4-di-tert-butyl-3,6-dihydroxyphenyl)phosphonate contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 358.41 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), Diethyl (2,4-di-tert-butyl-3,6-dihydroxyphenyl)phosphonate 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.
