Chemical Structure

alpha-Chlorothioanisole CAS 7205-91-6 chemical structure

Description

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.

alpha-Chlorothioanisole (CAS 7205-91-6) is a high-purity analytical reference standard with the molecular formula C7H7ClS and a molecular weight of 158.65 g/mol.

alpha-Chlorothioanisole (C7H7ClS) contains sulfur-containing functionality, 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.

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