2-(Phenylsulfanyl)ethane-1-thiol CAS 17109-66-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(Phenylsulfanyl)ethane-1-thiol.

2-(Phenylsulfanyl)ethane-1-thiol (CAS 17109-66-9) is a high-purity analytical reference standard with the molecular formula C8H10S2 and a molecular weight of 170.29 g/mol.

Owing to sulfur-containing functionality, an aromatic ring system, 2-(Phenylsulfanyl)ethane-1-thiol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 170.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
