Chemical Structure
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.
(E)-N-((3,3-Difluorocyclobutyl)methylene)-2-methylpropane-2-sulfinamide (CAS 2881013-27-8), molecular formula C9H15F2NOS and molecular weight 223.28 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (E)-N-((3,3-Difluorocyclobutyl)methylene)-2-methylpropane-2-sulfinamide (C9H15F2NOS) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
