Chemical Structure
Description
As a certified reference material (CRM), 3,3-Dimethyl-2-phenyl-3,4-dihydrobenzo[e][1,4,2]oxazaphosphinine 2-oxide 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 3,3-Dimethyl-2-phenyl-3,4-dihydrobenzo[e][1,4,2]oxazaphosphinine 2-oxide (CAS 220976-20-5), a certified reference material (molecular formula C15H16NO2P, MW 273.27 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage, 3,3-Dimethyl-2-phenyl-3,4-dihydrobenzo[e][1,4,2]oxazaphosphinine 2-oxide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 273.27 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.
