Chemical Structure

1-(2-Fluorophenyl)ethane-1-thiol CAS 1152542-65-8 chemical structure

Description

Structurally, 1-(2-Fluorophenyl)ethane-1-thiol (C8H9FS) contains sulfur-containing functionality, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 156.22 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

CATO supplies 1-(2-Fluorophenyl)ethane-1-thiol (CAS 1152542-65-8), a certified reference material (molecular formula C8H9FS, MW 156.22 g/mol) for analytical method development and quality control.

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.
