Chemical Structure

3,4-Diphenylthiophene CAS 95831-30-4 chemical structure

Description

3,4-Diphenylthiophene (CAS 95831-30-4), molecular formula C16H10Br2S and molecular weight 394.12 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3,4-Diphenylthiophene (C16H10Br2S) contains sulfur-containing functionality, bromine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 394.12 g/mol, it falls into the moderately-high-molecular-weight range. 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), 3,4-Diphenylthiophene 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.
