As a certified reference material (CRM), (Phenylmethylene)bis(phenylsulfane) 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.
(Phenylmethylene)bis(phenylsulfane) (CAS 7695-69-4), molecular formula C19H16S2 and molecular weight 308.46 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (Phenylmethylene)bis(phenylsulfane) (C19H16S2) is characterized by sulfur-containing functionality, a polycyclic aromatic system. 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.
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.
