Chemical Structure
Description
CATO supplies tert-Butyl 2,4-dichloropyrimidine-5-carboxylate (CAS 1786411-92-4), a certified reference material (molecular formula C9H10Cl2N2O2, MW 249.09 g/mol) for analytical method development and quality control.
Structurally, tert-Butyl 2,4-dichloropyrimidine-5-carboxylate (C9H10Cl2N2O2) 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 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 249.09 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
