Chemical Structure
Description
As a certified reference material (CRM), <I>N</I>-methoxy-<I>N</I>-methyl(triphenylphosphineylidene)acetamide 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.
<I>N</I>-methoxy-<I>N</I>-methyl(triphenylphosphineylidene)acetamide (CAS 129986-67-0) is a high-purity analytical reference standard with the molecular formula C22H40NO2P and a molecular weight of 381.53 g/mol.
<I>N</I>-methoxy-<I>N</I>-methyl(triphenylphosphineylidene)acetamide (C22H40NO2P) contains an amide group, organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
