Description
As a certified reference material (CRM), 2,3-dichloro-4-fluorobenzaldehyde 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.
2,3-dichloro-4-fluorobenzaldehyde (CAS 845907-07-5) is a high-purity analytical reference standard with the molecular formula C7H3Cl2FO and a molecular weight of 193.00 g/mol.
Based on its molecular formula C7H3Cl2FO, 2,3-dichloro-4-fluorobenzaldehyde contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 193.00 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.
