Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 4-(Cyclopropanesulfonyl)aniline is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 197.25 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.
CATO supplies 4-(Cyclopropanesulfonyl)aniline (CAS 1147558-13-1), a certified reference material (molecular formula C9H11NO2S, MW 197.25 g/mol) for analytical method development and quality control.
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.
