Chemical Structure

Pteridine CAS 91-18-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 132.12 g/mol gives Pteridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Pteridine (CAS 91-18-9), molecular formula C6H4N4 and molecular weight 132.12 g/mol, is a CATO reference standard with documented purity and traceability.

Pteridine (C6H4N4) contains a nitrile group, an aromatic ring system. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
