1-Methyl-4-(3,4,4-trifluorobut-3-ene-1-sulfonyl)benzene CAS 343374-89-0

Description

1-Methyl-4-(3,4,4-trifluorobut-3-ene-1-sulfonyl)benzene (CAS 343374-89-0), molecular formula C11H11F3O2S and molecular weight 264.26 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-Methyl-4-(3,4,4-trifluorobut-3-ene-1-sulfonyl)benzene (C11H11F3O2S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

As a certified reference material (CRM), 1-Methyl-4-(3,4,4-trifluorobut-3-ene-1-sulfonyl)benzene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
