2-Chloro-6-fluorobenzene-1-thiol CAS 1208075-39-1

Description

The occurrence of 2-Chloro-6-fluorobenzene-1-thiol is closely related to sulfur-containing functionality, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Chloro-6-fluorobenzene-1-thiol (CAS 1208075-39-1), molecular formula C6H4ClFS and molecular weight 162.61 g/mol, is a CATO reference standard with documented purity and traceability.

2-Chloro-6-fluorobenzene-1-thiol (C6H4ClFS) contains sulfur-containing functionality, fluorine/chlorine 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. 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.

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.
