Chemical Structure

Bis(2-chloroethyl) sulfone CAS 471-03-4 chemical structure

Description

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.

Bis(2-chloroethyl) sulfone (CAS 471-03-4), molecular formula C4H8Cl2O2S and molecular weight 191.08 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Bis(2-chloroethyl) sulfone (C4H8Cl2O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 191.08 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

As a certified reference material (CRM), Bis(2-chloroethyl) sulfone 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.
