Description
Compared with other compounds in its class, the molecular weight of 249.33 g/mol gives <I>N</I>,<I>N</I>-diethylphosphoramidite di-tert-butyl ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies <I>N</I>,<I>N</I>-diethylphosphoramidite di-tert-butyl ester (CAS 117924-33-1), a certified reference material (molecular formula C12H28NO2P, MW 249.33 g/mol) for analytical method development and quality control.
Structurally, <I>N</I>,<I>N</I>-diethylphosphoramidite di-tert-butyl ester (C12H28NO2P) contains an amide group, organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of -0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 249.33 g/mol, it falls into the medium-molecular-weight range. 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.
As a certified reference material (CRM), <I>N</I>,<I>N</I>-diethylphosphoramidite di-tert-butyl ester 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.
