2-{7,8-dimethoxy-4-oxo-3H,4H,5H-pyrimido[5,4-b]indol-3-yl}acetic acid CAS 1326864-64-5

Description

The occurrence of 2-{7,8-dimethoxy-4-oxo-3H,4H,5H-pyrimido[5,4-b]indol-3-yl}acetic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-{7,8-dimethoxy-4-oxo-3H,4H,5H-pyrimido[5,4-b]indol-3-yl}acetic acid (CAS 1326864-64-5), molecular formula C14H13N3O5 and molecular weight 303.27 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-{7,8-dimethoxy-4-oxo-3H,4H,5H-pyrimido[5,4-b]indol-3-yl}acetic acid (C14H13N3O5) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 303.27 g/mol, it falls into the moderately-high-molecular-weight range. 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).

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.
