Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Benzofuran-5-yldimethylphosphine oxide.
CATO supplies Benzofuran-5-yldimethylphosphine oxide (CAS 2748288-54-0), a certified reference material (molecular formula C10H11O2P, MW 194.17 g/mol) for analytical method development and quality control.
Based on its molecular formula C10H11O2P, Benzofuran-5-yldimethylphosphine oxide contains organophosphorus functionality, 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 194.17 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Benzofuran-5-yldimethylphosphine 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.
