Description

Compared with other compounds in its class, the molecular weight of 404.52 g/mol gives 3-Methylsulfonyl-2,3',4',5,6-pentachlorobiphenyl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-Methylsulfonyl-2,3',4',5,6-pentachlorobiphenyl (CAS 116807-23-9), molecular formula C13H7Cl5O2S and molecular weight 404.52 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3-Methylsulfonyl-2,3',4',5,6-pentachlorobiphenyl (C13H7Cl5O2S) 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 404.52 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
