N-(4-methoxyphenyl)-9-methyl-5,6,7,9-tetrahydropyrazolo[3,4-b]pyrimido[4,5-d]azepin-2-amine CAS 1242899-52-0

Description

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.

N-(4-methoxyphenyl)-9-methyl-5,6,7,9-tetrahydropyrazolo[3,4-b]pyrimido[4,5-d]azepin-2-amine (CAS 1242899-52-0), molecular formula C17H18N6O and molecular weight 322.36 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, N-(4-methoxyphenyl)-9-methyl-5,6,7,9-tetrahydropyrazolo[3,4-b]pyrimido[4,5-d]azepin-2-amine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 322.36 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
