tert-Butyl 4-(5-amino-6-chloropyrimidin-4-yl)piperazine-1-carboxylate CAS 853679-43-3 chemical structure

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

tert-Butyl 4-(5-amino-6-chloropyrimidin-4-yl)piperazine-1-carboxylate (CAS 853679-43-3) is a high-purity analytical reference standard with the molecular formula C13H20ClN5O2 and a molecular weight of 313.78 g/mol.

tert-Butyl 4-(5-amino-6-chloropyrimidin-4-yl)piperazine-1-carboxylate (C13H20ClN5O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

CATO manufactures tert-Butyl 4-(5-amino-6-chloropyrimidin-4-yl)piperazine-1-carboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
