Description
CATO supplies 3-Cyclopropoxy-5-formylisonicotinonitrile (CAS 1243384-79-3), a certified reference material (molecular formula C10H8N2O2, MW 188.18 g/mol) for analytical method development and quality control.
Based on its molecular formula C10H8N2O2, 3-Cyclopropoxy-5-formylisonicotinonitrile contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 188.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
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-Cyclopropoxy-5-formylisonicotinonitrile 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.
