Chemical Structure
Description
3-(2,4-dichloro-6,7-dihydropyrimido[5,4-b][1,4]oxazin-8-yl)propyl methanesulfonate (CAS 2756855-60-2) is a high-purity analytical reference standard with the molecular formula C10H19Cl2N3O4S and a molecular weight of 348.25 g/mol.
Structurally, 3-(2,4-dichloro-6,7-dihydropyrimido[5,4-b][1,4]oxazin-8-yl)propyl methanesulfonate (C10H19Cl2N3O4S) contains an amide group, a sulfone group, a carboxylic acid 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 348.25 g/mol, it falls into the moderately-high-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.
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.
