8-Hydroxy-6,7-dihydro-5H-cyclopenta[d]pyrazolo[1,5-a]pyrimidine-3-carboxylic acid CAS 1310263-36-5

Description

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.

8-Hydroxy-6,7-dihydro-5H-cyclopenta[d]pyrazolo[1,5-a]pyrimidine-3-carboxylic acid (CAS 1310263-36-5) is a high-purity analytical reference standard with the molecular formula C10H9N3O3 and a molecular weight of 219.20 g/mol.

The molecular framework of 8-Hydroxy-6,7-dihydro-5H-cyclopenta[d]pyrazolo[1,5-a]pyrimidine-3-carboxylic acid (C10H9N3O3) 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 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.
