2-Fluoro-3-methylbenzenethiol CAS 1823052-76-1

Description

The occurrence of 2-Fluoro-3-methylbenzenethiol is closely related to sulfur-containing functionality, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Fluoro-3-methylbenzenethiol (CAS 1823052-76-1) is a high-purity analytical reference standard with the molecular formula C7H7FS and a molecular weight of 142.19 g/mol.

2-Fluoro-3-methylbenzenethiol (C7H7FS) contains sulfur-containing functionality, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
