Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 151.23 g/mol gives n-Methylbutane-1-sulfonamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies n-Methylbutane-1-sulfonamide (CAS 16867-25-7), a certified reference material (molecular formula C5H13NO2S, MW 151.23 g/mol) for analytical method development and quality control.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, n-Methylbutane-1-sulfonamide is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 151.23 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.
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.
