Description

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

4-Phenylthiophenol 4-phenylbenzene-1-thiol Biphenyl-4-thiol 1,1'-Biphenyl-4-thiol, 4-Biphenylylthiol 4-Mercaptobiphenyl 19813-90-2 (CAS 19813-90-2) is a high-purity analytical reference standard with the molecular formula C12H22S and a molecular weight of 198.37 g/mol.

The molecular framework of 4-Phenylthiophenol 4-phenylbenzene-1-thiol Biphenyl-4-thiol 1,1'-Biphenyl-4-thiol, 4-Biphenylylthiol 4-Mercaptobiphenyl 19813-90-2 (C12H22S) is characterized by sulfur-containing functionality. 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
