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 6-Boronopyrazolo[1,5-a]pyrimidine-3-carboxylic acid.
6-Boronopyrazolo[1,5-a]pyrimidine-3-carboxylic acid (CAS 1065083-05-7), molecular formula C7H6BN3O4 and molecular weight 206.95 g/mol, is a CATO reference standard with documented purity and traceability.
6-Boronopyrazolo[1,5-a]pyrimidine-3-carboxylic acid (C7H6BN3O4) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
