(3-Fluorophenyl)methanethiol CAS 40096-23-9

Description

Compared with other compounds in its class, the molecular weight of 142.19 g/mol gives (3-Fluorophenyl)methanethiol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(3-Fluorophenyl)methanethiol (CAS 40096-23-9) is a high-purity analytical reference standard with the molecular formula C7H7FS and a molecular weight of 142.19 g/mol.

Owing to sulfur-containing functionality, fluorine substitution, an aromatic ring system, (3-Fluorophenyl)methanethiol is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 142.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
