Description
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 Methyl (ethyldiphenylphosphoranylidene)carbamate (CAS 127802-82-8), a certified reference material (molecular formula C16H18NO2P, MW 287.29 g/mol) for analytical method development and quality control.
Structurally, Methyl (ethyldiphenylphosphoranylidene)carbamate (C16H18NO2P) contains a nitrogen-containing heterocyclic scaffold, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.5, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 287.29 g/mol, it falls into the medium-molecular-weight range. 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).
CATO manufactures Methyl (ethyldiphenylphosphoranylidene)carbamate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
