Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 4-(3-ethyl-3H-[1,2,3]triazolo[4,5-d]pyrimidin-7-yl)piperazine-1-carboxylate.
Ethyl 4-(3-ethyl-3H-[1,2,3]triazolo[4,5-d]pyrimidin-7-yl)piperazine-1-carboxylate (CAS 899978-13-3) is a high-purity analytical reference standard with the molecular formula C13H19N7O2 and a molecular weight of 305.34 g/mol.
The molecular framework of Ethyl 4-(3-ethyl-3H-[1,2,3]triazolo[4,5-d]pyrimidin-7-yl)piperazine-1-carboxylate (C13H19N7O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
