Chemical Structure
Description
The occurrence of 4-Amino-5-cyano-2-methylpyrimidine 4-amino-2-methylpyrimidine-5-carbonitrile 698-29-3 is closely related to a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Amino-5-cyano-2-methylpyrimidine 4-amino-2-methylpyrimidine-5-carbonitrile 698-29-3 (CAS 698-29-3), molecular formula C6H12N4 and molecular weight 140.19 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-Amino-5-cyano-2-methylpyrimidine 4-amino-2-methylpyrimidine-5-carbonitrile 698-29-3 (C6H12N4) contains a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 140.19 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.
