3-{5,7-dimethyl-4H,5H,6H,7H-pyrazolo[1,5-a]pyrimidin-6-yl}propanoic acid CAS 2059950-54-6 chemical structure

Description

The occurrence of 3-{5,7-dimethyl-4H,5H,6H,7H-pyrazolo[1,5-a]pyrimidin-6-yl}propanoic acid 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 3-{5,7-dimethyl-4H,5H,6H,7H-pyrazolo[1,5-a]pyrimidin-6-yl}propanoic acid (CAS 2059950-54-6), a certified reference material (molecular formula C11H17N3O2, MW 223.27 g/mol) for analytical method development and quality control.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 3-{5,7-dimethyl-4H,5H,6H,7H-pyrazolo[1,5-a]pyrimidin-6-yl}propanoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 223.27 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).

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.

As a certified reference material (CRM), 3-{5,7-dimethyl-4H,5H,6H,7H-pyrazolo[1,5-a]pyrimidin-6-yl}propanoic acid 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.
