Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4,5-Dichloro-2-(trifluoromethyl)benzaldehyde.
CATO supplies 4,5-Dichloro-2-(trifluoromethyl)benzaldehyde (CAS 134099-43-7), a certified reference material (molecular formula C8H3Cl2F3O, MW 243.01 g/mol) for analytical method development and quality control.
The molecular framework of 4,5-Dichloro-2-(trifluoromethyl)benzaldehyde (C8H3Cl2F3O) is characterized by a hydroxyl group, an ether linkage, fluorine/chlorine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
