5-(2-chlorobenzyl)-2-hydroxy-3-nitrobenzaldehyde CAS 292644-32-7

Description

The occurrence of 5-(2-chlorobenzyl)-2-hydroxy-3-nitrobenzaldehyde is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-(2-chlorobenzyl)-2-hydroxy-3-nitrobenzaldehyde (CAS 292644-32-7), molecular formula C14H10ClNO4 and molecular weight 291.69 g/mol, is a CATO reference standard with documented purity and traceability.

5-(2-chlorobenzyl)-2-hydroxy-3-nitrobenzaldehyde (C14H10ClNO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 5-(2-chlorobenzyl)-2-hydroxy-3-nitrobenzaldehyde 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.
