Chemical Structure

4-Ethylbenzaldehyde CAS 4748-78-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 134.18 g/mol gives 4-Ethylbenzaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Ethylbenzaldehyde (CAS 4748-78-1), molecular formula C9H10O and molecular weight 134.18 g/mol, is a CATO reference standard with documented purity and traceability.

4-Ethylbenzaldehyde (C9H10O) contains a hydroxyl group, an ether linkage, an aromatic ring system. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
