Chemical Structure
Description
CATO supplies 4-(5,6-Dimethoxy-2H-indazol-2-yl)-N,N-diethylaniline (CAS 58522-42-2), a certified reference material (molecular formula C19H23N3O2, MW 325.40 g/mol) for analytical method development and quality control.
4-(5,6-Dimethoxy-2H-indazol-2-yl)-N,N-diethylaniline (C19H23N3O2) contains a steroid core, an amide 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.
