Chemical Structure
Description
The occurrence of 4-Pyrimidin-2-yl-piperazine-1,3-dicarboxylic acid 1-tert-butyl ester is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Pyrimidin-2-yl-piperazine-1,3-dicarboxylic acid 1-tert-butyl ester (CAS 1185313-57-8), molecular formula C14H19ClN4O4 and molecular weight 342.78 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C14H19ClN4O4, 4-Pyrimidin-2-yl-piperazine-1,3-dicarboxylic acid 1-tert-butyl ester contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 342.78 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.
