Compared with other compounds in its class, the molecular weight of 134.18 g/mol gives 2,4-Dimethylbenzaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,4-Dimethylbenzaldehyde (CAS 15764-16-6) is a high-purity analytical reference standard with the molecular formula C9H10O and a molecular weight of 134.18 g/mol.
The molecular framework of 2,4-Dimethylbenzaldehyde (C9H10O) is characterized by a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), 2,4-Dimethylbenzaldehyde 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.
