2-Amino-4-phenylpyrimidine-5-carboxylic acid CAS 91093-42-4

Description

Compared with other compounds in its class, the molecular weight of 215.21 g/mol gives 2-Amino-4-phenylpyrimidine-5-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Amino-4-phenylpyrimidine-5-carboxylic acid (CAS 91093-42-4), molecular formula C11H9N3O2 and molecular weight 215.21 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Amino-4-phenylpyrimidine-5-carboxylic acid (C11H9N3O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
