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-Chloro-2-(ethylthio)pyridine (CAS 102645-38-5), a certified reference material (molecular formula C7H8ClNS, MW 173.66 g/mol) for analytical method development and quality control.
Owing to a nitrile group, sulfur-containing functionality, chlorine substitution, an aromatic ring system, 5-Chloro-2-(ethylthio)pyridine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 173.66 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
