1-Phenyldibenzothiophene CAS 3776-90-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Phenyldibenzothiophene.

CATO supplies 1-Phenyldibenzothiophene (CAS 3776-90-7), a certified reference material (molecular formula C18H12S, MW 260.35 g/mol) for analytical method development and quality control.

Owing to sulfur-containing functionality, a polycyclic aromatic system, 1-Phenyldibenzothiophene is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 260.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
