Chemical Structure

4,4'-Bis(mercaptomethyl) Biphenyl CAS 43012-19-7 chemical structure

Description

The molecular framework of 4,4'-Bis(mercaptomethyl) Biphenyl (C14H14S2) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO supplies 4,4'-Bis(mercaptomethyl) Biphenyl (CAS 43012-19-7), a certified reference material (molecular formula C14H14S2, MW 246.39 g/mol) for analytical method development and quality control.

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.

As a certified reference material (CRM), 4,4'-Bis(mercaptomethyl) Biphenyl 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.
