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.
N,N-DI-BOc-2-amino-3,5-dibromopyrazine (CAS 1190001-75-2), molecular formula C14H19Br2N3O4 and molecular weight 453.13 g/mol, is a CATO reference standard with documented purity and traceability.
N,N-DI-BOc-2-amino-3,5-dibromopyrazine (C14H19Br2N3O4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine 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.
As a certified reference material (CRM), N,N-DI-BOc-2-amino-3,5-dibromopyrazine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
