Chemical Structure

5-chlorothiophen-3-amine CAS 123403-75-8 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.

CATO supplies 5-chlorothiophen-3-amine (CAS 123403-75-8), a certified reference material (molecular formula C4H8ClNS, MW 137.63 g/mol) for analytical method development and quality control.

5-chlorothiophen-3-amine (C4H8ClNS) contains sulfur-containing functionality, chlorine substitution. 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.
