Chemical Structure
Description
As a certified reference material (CRM), 3-Amino-5-fluoroisonicotinaldehyde 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.
3-Amino-5-fluoroisonicotinaldehyde (CAS 1289147-24-5) is a high-purity analytical reference standard with the molecular formula C6H5FN2O and a molecular weight of 140.12 g/mol.
Owing to an amide group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 3-Amino-5-fluoroisonicotinaldehyde is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 140.12 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.
