(3,5-Diamino-6-chloropyrazin-2-yl)(1H-imidazol-1-yl)methanone CAS 76962-94-2

Description

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.

(3,5-Diamino-6-chloropyrazin-2-yl)(1H-imidazol-1-yl)methanone (CAS 76962-94-2), molecular formula C8H7ClN6O and molecular weight 238.63 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (3,5-Diamino-6-chloropyrazin-2-yl)(1H-imidazol-1-yl)methanone (C8H7ClN6O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 238.63 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
