(E)-2-(4-Methylphenyl)ethylenesulfonyl chloride CAS 98821-28-4

Description

Compared with other compounds in its class, the molecular weight of 216.68 g/mol gives (E)-2-(4-Methylphenyl)ethylenesulfonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies (E)-2-(4-Methylphenyl)ethylenesulfonyl chloride (CAS 98821-28-4), a certified reference material (molecular formula C9H9ClO2S, MW 216.68 g/mol) for analytical method development and quality control.

(E)-2-(4-Methylphenyl)ethylenesulfonyl chloride (C9H9ClO2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), (E)-2-(4-Methylphenyl)ethylenesulfonyl 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.
