3-Amino-8-methyl-2-sulfanylidene-1H,2H,3H,4H,5H-pyrimido[5,4-b]indol-4-one CAS 1351398-13-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Amino-8-methyl-2-sulfanylidene-1H,2H,3H,4H,5H-pyrimido[5,4-b]indol-4-one.

3-Amino-8-methyl-2-sulfanylidene-1H,2H,3H,4H,5H-pyrimido[5,4-b]indol-4-one (CAS 1351398-13-4) is a high-purity analytical reference standard with the molecular formula C11H10N4OS and a molecular weight of 246.29 g/mol.

3-Amino-8-methyl-2-sulfanylidene-1H,2H,3H,4H,5H-pyrimido[5,4-b]indol-4-one (C11H10N4OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; 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.
