Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 1-Chloro-4-(methylsulfanyl)butane (CAS 27160-24-3), a certified reference material (molecular formula C5H11ClS, MW 138.66 g/mol) for analytical method development and quality control.
Owing to sulfur-containing functionality, chlorine substitution, 1-Chloro-4-(methylsulfanyl)butane is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 138.66 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.
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.
