Chemical Structure

S-Methyl 2,5-difluorobenzothioate CAS 1146210-64-1 chemical structure

Description

CATO supplies S-Methyl 2,5-difluorobenzothioate (CAS 1146210-64-1), a certified reference material (molecular formula C8H6F2OS, MW 188.19 g/mol) for analytical method development and quality control.

Based on its molecular formula C8H6F2OS, S-Methyl 2,5-difluorobenzothioate contains sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 188.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
