Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 232.73 g/mol gives ((4-Chlorobutyl)sulfonyl)benzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
((4-Chlorobutyl)sulfonyl)benzene (CAS 33451-35-3), molecular formula C10H13ClO2S and molecular weight 232.73 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of ((4-Chlorobutyl)sulfonyl)benzene (C10H13ClO2S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
