Description

Compared with other compounds in its class, the molecular weight of 278.26 g/mol gives 43024-67-5 7-Aminopyrazolo[1,5-a]pyrimidine-3,6-dicarboxylic Acid 3,6-Diethyl Ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

43024-67-5 7-Aminopyrazolo[1,5-a]pyrimidine-3,6-dicarboxylic Acid 3,6-Diethyl Ester (CAS 43024-67-5) is a high-purity analytical reference standard with the molecular formula C12H14N4O4 and a molecular weight of 278.26 g/mol.

The molecular framework of 43024-67-5 7-Aminopyrazolo[1,5-a]pyrimidine-3,6-dicarboxylic Acid 3,6-Diethyl Ester (C12H14N4O4) 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).

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.
