Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(Trifluoromethylsulfonyl)benzaldehyde 650-89-5 p-[(Trifluoromethyl)sulfonyl]benzaldehyde.
4-(Trifluoromethylsulfonyl)benzaldehyde 650-89-5 p-[(Trifluoromethyl)sulfonyl]benzaldehyde (CAS 650-89-5) is a high-purity analytical reference standard with the molecular formula C8H5F3O3S and a molecular weight of 238.18 g/mol.
The molecular framework of 4-(Trifluoromethylsulfonyl)benzaldehyde 650-89-5 p-[(Trifluoromethyl)sulfonyl]benzaldehyde (C8H5F3O3S) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
