2-((3,5-Dichlorophenyl)sulfonyl)ethan-1-ol CAS 101079-90-7

Description

Compared with other compounds in its class, the molecular weight of 255.12 g/mol gives 2-((3,5-Dichlorophenyl)sulfonyl)ethan-1-ol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-((3,5-Dichlorophenyl)sulfonyl)ethan-1-ol (CAS 101079-90-7), molecular formula C8H8Cl2O3S and molecular weight 255.12 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 2-((3,5-Dichlorophenyl)sulfonyl)ethan-1-ol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 255.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
