2-[(2,4-Difluorophenyl)carbamoyl]thiophen-3-yl N,N-dimethylsulfamate CAS 338794-13-1

Description

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.

2-[(2,4-Difluorophenyl)carbamoyl]thiophen-3-yl N,N-dimethylsulfamate (CAS 338794-13-1), molecular formula C13H12F2N2O4S2 and molecular weight 362.37 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, 2-[(2,4-Difluorophenyl)carbamoyl]thiophen-3-yl N,N-dimethylsulfamate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 362.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
