Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

3',5'-Dimethyl 6'-amino-2'-methyl-2-oxo-1,2-dihydrospiro[indole-3,4'-pyran]-3',5'-dicarboxylate (CAS 401461-50-5) is a high-purity analytical reference standard with the molecular formula C17H16N2O6 and a molecular weight of 344.32 g/mol.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 3',5'-Dimethyl 6'-amino-2'-methyl-2-oxo-1,2-dihydrospiro[indole-3,4'-pyran]-3',5'-dicarboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 344.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
