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.
(R)-N-((S)-1-(4-Bromothiophen-2-yl)ethyl)-2-methylpropane-2-sulfinamide (CAS 2654745-63-6), molecular formula C10H16BrNOS2 and molecular weight 310.27 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (R)-N-((S)-1-(4-Bromothiophen-2-yl)ethyl)-2-methylpropane-2-sulfinamide (C10H16BrNOS2) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 310.27 g/mol, it falls into the moderately-high-molecular-weight range. 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.
