Chemical Structure

4-Phenyldibenzothiophene CAS 98251-31-1 chemical structure

Description

4-Phenyldibenzothiophene (CAS 98251-31-1), molecular formula C18H12S and molecular weight 260.35 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-Phenyldibenzothiophene (C18H12S) 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).

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

As a certified reference material (CRM), 4-Phenyldibenzothiophene 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.
