Chemical Structure
Description
4-(Dibenzylamino)-2-methylbenzaldehyde (CAS 1424-65-3), molecular formula C22H21NO and molecular weight 315.41 g/mol, is a CATO reference standard with documented purity and traceability.
4-(Dibenzylamino)-2-methylbenzaldehyde (C22H21NO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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-(Dibenzylamino)-2-methylbenzaldehyde 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.
