Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-(tert-Butoxy)-4-cyclopropoxypyridine-2-sulfonamide.
CATO supplies 6-(tert-Butoxy)-4-cyclopropoxypyridine-2-sulfonamide (CAS 1243393-22-7), a certified reference material (molecular formula C12H18N2O4S, MW 286.35 g/mol) for analytical method development and quality control.
6-(tert-Butoxy)-4-cyclopropoxypyridine-2-sulfonamide (C12H18N2O4S) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
