Chemical Structure

2,4-Bis(trichloromethyl)-4H-benzo[d][1,3]dioxine-6-sulfonyl chloride CAS 61720-32-9 chemical structure

Description

2,4-Bis(trichloromethyl)-4H-benzo[d][1,3]dioxine-6-sulfonyl chloride (CAS 61720-32-9) is a high-purity analytical reference standard with the molecular formula C10H5Cl7O4S and a molecular weight of 469.38 g/mol.

The molecular framework of 2,4-Bis(trichloromethyl)-4H-benzo[d][1,3]dioxine-6-sulfonyl chloride (C10H5Cl7O4S) 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), 2,4-Bis(trichloromethyl)-4H-benzo[d][1,3]dioxine-6-sulfonyl 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.
