2-Iodo-4-nitrobenzaldehyde CAS 101421-31-2

Description

Compared with other compounds in its class, the molecular weight of 277.02 g/mol gives 2-Iodo-4-nitrobenzaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Iodo-4-nitrobenzaldehyde (CAS 101421-31-2), molecular formula C7H4INO3 and molecular weight 277.02 g/mol, is a CATO reference standard with documented purity and traceability.

2-Iodo-4-nitrobenzaldehyde (C7H4INO3) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine 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. 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), 2-Iodo-4-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.
