3-Chloropropyl 4-methylbenzenesulfonate CAS 632-02-0

Description

Compared with other compounds in its class, the molecular weight of 248.73 g/mol gives 3-Chloropropyl 4-methylbenzenesulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-Chloropropyl 4-methylbenzenesulfonate (CAS 632-02-0) is a high-purity analytical reference standard with the molecular formula C10H13ClO3S and a molecular weight of 248.73 g/mol.

The molecular framework of 3-Chloropropyl 4-methylbenzenesulfonate (C10H13ClO3S) 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.

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), 3-Chloropropyl 4-methylbenzenesulfonate 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.
