4,6-Dichloro-2-methoxynicotinaldehyde CAS 2247102-25-4 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 4,6-Dichloro-2-methoxynicotinaldehyde.

4,6-Dichloro-2-methoxynicotinaldehyde (CAS 2247102-25-4), molecular formula C7H5Cl2NO2 and molecular weight 206.03 g/mol, is a CATO reference standard with documented purity and traceability.

4,6-Dichloro-2-methoxynicotinaldehyde (C7H5Cl2NO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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), 4,6-Dichloro-2-methoxynicotinaldehyde 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.
