Chemical Structure

Pteridin-4-amine CAS 6973-01-9 chemical structure

Description

Pteridin-4-amine (CAS 6973-01-9), molecular formula C6H5N5 and molecular weight 147.14 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Pteridin-4-amine (C6H5N5) contains a nitrile group, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 147.14 g/mol, it falls into the low-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.
