Chemical Structure
Description
The occurrence of 4,6-Dichloro-2-hydrazinylpyrimidine is closely related to a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4,6-Dichloro-2-hydrazinylpyrimidine (CAS 887592-69-0), molecular formula C4H4Cl2N4 and molecular weight 179.01 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C4H4Cl2N4, 4,6-Dichloro-2-hydrazinylpyrimidine contains a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 179.01 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
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.
