3-Bromo-2,5-dimethylpyrazolo[1,5-a]pyrimidine-7-carboxylic acid CAS 937601-34-8

Description

3-Bromo-2,5-dimethylpyrazolo[1,5-a]pyrimidine-7-carboxylic acid (CAS 937601-34-8), molecular formula C9H8BrN3O2 and molecular weight 270.08 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-Bromo-2,5-dimethylpyrazolo[1,5-a]pyrimidine-7-carboxylic acid (C9H8BrN3O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
