Chemical Structure
Description
CATO supplies 7-Bromospiro[chromane-2,3'-thietan]-4-one 1',1'-dioxide (CAS 2200003-26-3), a certified reference material (molecular formula C11H15BrO4S, MW 323.20 g/mol) for analytical method development and quality control.
The molecular framework of 7-Bromospiro[chromane-2,3'-thietan]-4-one 1',1'-dioxide (C11H15BrO4S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
