Chemical Structure
Description
4-(4-Iodo-1H-pyrazol-1-yl)cyclohexanol (CAS 1801330-98-2), molecular formula C9H13IN2O and molecular weight 292.12 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C9H13IN2O, 4-(4-Iodo-1H-pyrazol-1-yl)cyclohexanol contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 292.12 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
