[2-(Phenylsulfanyl)pyridin-3-yl]methyl N-(2-methylphenyl)carbamate CAS 339278-64-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including [2-(Phenylsulfanyl)pyridin-3-yl]methyl N-(2-methylphenyl)carbamate.

[2-(Phenylsulfanyl)pyridin-3-yl]methyl N-(2-methylphenyl)carbamate (CAS 339278-64-7), molecular formula C20H18N2O2S and molecular weight 350.43 g/mol, is a CATO reference standard with documented purity and traceability.

[2-(Phenylsulfanyl)pyridin-3-yl]methyl N-(2-methylphenyl)carbamate (C20H18N2O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
