Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(P-tolyl)-N-(2-(p-tolylsulfinyl)ethyl)acetamide.
2-(P-tolyl)-N-(2-(p-tolylsulfinyl)ethyl)acetamide (CAS 477710-74-0), molecular formula C18H21NO2S and molecular weight 315.43 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C18H21NO2S, 2-(P-tolyl)-N-(2-(p-tolylsulfinyl)ethyl)acetamide contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 315.43 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.
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.
