Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO supplies 2347AF 895261-67-3 C10H13NO5S2 Methyl 3-(morpholin-4-ylsulfonyl)thiophene-2-carboxylate (CAS 895261-67-3), a certified reference material (molecular formula C10H13NO5S2, MW 291.34 g/mol) for analytical method development and quality control.
2347AF 895261-67-3 C10H13NO5S2 Methyl 3-(morpholin-4-ylsulfonyl)thiophene-2-carboxylate (C10H13NO5S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
