Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-amino-6-chloro-2-methyl-pyrimidine-5-carbaldehyde (CAS 51290-87-0) is a high-purity analytical reference standard with the molecular formula C6H12ClN3O and a molecular weight of 177.63 g/mol.
Structurally, 4-amino-6-chloro-2-methyl-pyrimidine-5-carbaldehyde (C6H12ClN3O) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 177.63 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.
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.
