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 2-(2-chloro-4-fluorophenyl)acetaldehyde.
2-(2-chloro-4-fluorophenyl)acetaldehyde (CAS 864437-19-4) is a high-purity analytical reference standard with the molecular formula C8H12ClFO and a molecular weight of 178.63 g/mol.
The molecular framework of 2-(2-chloro-4-fluorophenyl)acetaldehyde (C8H12ClFO) is characterized by a hydroxyl group, an ether linkage, fluorine/chlorine substitution. 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.
As a certified reference material (CRM), 2-(2-chloro-4-fluorophenyl)acetaldehyde 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.
