(2-Methylpropane-1,1-diyl)bis(phenylsulfane) CAS 54905-13-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2-Methylpropane-1,1-diyl)bis(phenylsulfane).

(2-Methylpropane-1,1-diyl)bis(phenylsulfane) (CAS 54905-13-4) is a high-purity analytical reference standard with the molecular formula C16H18S2 and a molecular weight of 274.44 g/mol.

The molecular framework of (2-Methylpropane-1,1-diyl)bis(phenylsulfane) (C16H18S2) 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).

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), (2-Methylpropane-1,1-diyl)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.
