Chemical Structure
Description
CATO supplies (1,1-Dioxidobenzo[b]thiophen-2-yl)methyl (2,5-dioxopyrrolidin-1-yl) carbonate (CAS 197244-91-0), a certified reference material (molecular formula C14H11NO7S, MW 337.30 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, (1,1-Dioxidobenzo[b]thiophen-2-yl)methyl (2,5-dioxopyrrolidin-1-yl) carbonate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 337.30 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.
