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.
7-Tert-Butyl 5-Ethyl 5,6-Dihydroimidazo[1,5-A]Pyrazine-5,7(8H)-Dicarboxylate (CAS 1822505-48-5) is a high-purity analytical reference standard with the molecular formula C14H21N3O4 and a molecular weight of 295.33 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 7-Tert-Butyl 5-Ethyl 5,6-Dihydroimidazo[1,5-A]Pyrazine-5,7(8H)-Dicarboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 295.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 7-Tert-Butyl 5-Ethyl 5,6-Dihydroimidazo[1,5-A]Pyrazine-5,7(8H)-Dicarboxylate 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.
