Description
CATO supplies 1031650-94-8 4-{[5-(4-Isopropylphenyl)-4-methyl-1,1-dioxido-3-oxoisothiazol-2(3H)-yl]methyl}benzoic acid MFCD14282140 (CAS 1031650-94-8), a certified reference material (molecular formula C21H21NO5S, MW 399.46 g/mol) for analytical method development and quality control.
1031650-94-8 4-{[5-(4-Isopropylphenyl)-4-methyl-1,1-dioxido-3-oxoisothiazol-2(3H)-yl]methyl}benzoic acid MFCD14282140 (C21H21NO5S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
