3-Methoxy-4-(difluoromethoxy)benzaldehyde CAS 162401-70-9 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 3-Methoxy-4-(difluoromethoxy)benzaldehyde.

3-Methoxy-4-(difluoromethoxy)benzaldehyde (CAS 162401-70-9) is a high-purity analytical reference standard with the molecular formula C9H8F2O3 and a molecular weight of 202.15 g/mol.

3-Methoxy-4-(difluoromethoxy)benzaldehyde (C9H8F2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), 3-Methoxy-4-(difluoromethoxy)benzaldehyde 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.
