Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 341.22 g/mol gives Benzene, 1-bromo-4-(methylsulfonyl)-2-(phenylmethoxy)- distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Benzene, 1-bromo-4-(methylsulfonyl)-2-(phenylmethoxy)- (CAS 2890194-36-0), molecular formula C14H13BrO3S and molecular weight 341.22 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Benzene, 1-bromo-4-(methylsulfonyl)-2-(phenylmethoxy)- (C14H13BrO3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
