2-Chloro-3,5-dimethoxybenzaldehyde CAS 112641-63-1

Description

The occurrence of 2-Chloro-3,5-dimethoxybenzaldehyde is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Chloro-3,5-dimethoxybenzaldehyde (CAS 112641-63-1), molecular formula C9H9ClO3 and molecular weight 200.62 g/mol, is a CATO reference standard with documented purity and traceability.

2-Chloro-3,5-dimethoxybenzaldehyde (C9H9ClO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine 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), 2-Chloro-3,5-dimethoxybenzaldehyde 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.
