Chemical Structure
Description
As a certified reference material (CRM), 2-Formyl-5-(methylsulphonyl)benzotrifluoride 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-Formyl-5-(methylsulphonyl)benzotrifluoride (CAS 1215310-75-0) is a high-purity analytical reference standard with the molecular formula C9H7F3O3S and a molecular weight of 252.21 g/mol.
The molecular framework of 2-Formyl-5-(methylsulphonyl)benzotrifluoride (C9H7F3O3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
