Chemical Structure
Description
Owing to sulfur-containing functionality, 3-Aminobutane-2-thiol is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 105.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
3-Aminobutane-2-thiol (CAS 4146-17-2) is a high-purity analytical reference standard with the molecular formula C4H11NS and a molecular weight of 105.20 g/mol.
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.
