Chemical Structure
Description
The occurrence of 3-(4-Iodo-1H-pyrazol-1-yl)butanenitrile is closely related to a nitrile group, iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-(4-Iodo-1H-pyrazol-1-yl)butanenitrile (CAS 1340316-77-9), molecular formula C7H8IN3 and molecular weight 261.06 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, iodine substitution, an aromatic ring system, 3-(4-Iodo-1H-pyrazol-1-yl)butanenitrile is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 261.06 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), 3-(4-Iodo-1H-pyrazol-1-yl)butanenitrile meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
