Chemical Structure
Description
The occurrence of Ethyl 3-(cyclopropylmethyl)-3H-[1,2,3]triazolo[4,5-d]pyrimidine-7-carboxylate is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Ethyl 3-(cyclopropylmethyl)-3H-[1,2,3]triazolo[4,5-d]pyrimidine-7-carboxylate (CAS 1923082-74-9), a certified reference material (molecular formula C11H13N5O2, MW 247.25 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl 3-(cyclopropylmethyl)-3H-[1,2,3]triazolo[4,5-d]pyrimidine-7-carboxylate (C11H13N5O2) is characterized by an amino-acid-derived structure, 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.
