Chemical Structure
Description
Based on its molecular formula C18H20NOP, 2-(Diphenylphosphoryl)-3,3-dimethylbutanenitrile contains a steroid core, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 297.33 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
2-(Diphenylphosphoryl)-3,3-dimethylbutanenitrile (CAS 62970-03-0), molecular formula C18H20NOP and molecular weight 297.33 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
