Chemical Structure
Description
The molecular framework of 4-(1-(1H-pyrazol-1-yl)cyclobutyl)butanoic acid (C11H16N2O2) 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 its high hydrophobicity (logP), 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).
4-(1-(1H-pyrazol-1-yl)cyclobutyl)butanoic acid (CAS 2489784-76-9) is a high-purity analytical reference standard with the molecular formula C11H16N2O2 and a molecular weight of 208.26 g/mol.
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.
