Chemical Structure
Description
The occurrence of 2-Chloro-1,3-difluorobenzene is closely related to fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Chloro-1,3-difluorobenzene (CAS 38361-37-4) is a high-purity analytical reference standard with the molecular formula C6H3ClF2 and a molecular weight of 148.54 g/mol.
Based on its molecular formula C6H3ClF2, 2-Chloro-1,3-difluorobenzene contains fluorine/chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 148.54 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), 2-Chloro-1,3-difluorobenzene 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.
