Chemical Structure
Description
The molecular framework of 2,5-Diisopropylbenzenesulfonyl chloride (C12H17ClO2S) 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
2,5-Diisopropylbenzenesulfonyl chloride (CAS 61942-72-1), molecular formula C12H17ClO2S and molecular weight 260.78 g/mol, is a CATO reference standard with documented purity and traceability.
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), 2,5-Diisopropylbenzenesulfonyl chloride 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.
