3-Methylsulfonyl-2,2',3',4',5,6-hexachlorobiphenyl CAS 149949-90-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Methylsulfonyl-2,2',3',4',5,6-hexachlorobiphenyl.

CATO supplies 3-Methylsulfonyl-2,2',3',4',5,6-hexachlorobiphenyl (CAS 149949-90-6), a certified reference material (molecular formula C13H6Cl6O2S, MW 438.97 g/mol) for analytical method development and quality control.

Structurally, 3-Methylsulfonyl-2,2',3',4',5,6-hexachlorobiphenyl (C13H6Cl6O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 438.97 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
