3-Isopentyl-1H-pyrazol-4-ol CAS 856058-38-3 chemical structure

Description

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.

3-Isopentyl-1H-pyrazol-4-ol (CAS 856058-38-3), molecular formula C8H14N2O and molecular weight 154.21 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C8H14N2O, 3-Isopentyl-1H-pyrazol-4-ol contains an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 154.21 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
