Description
TCI E0739 Ethyl 4-Hydroxy-3-methoxycinnamate (CAS 4046-02-0), more commonly known as ethyl ferulate, is the ethyl ester of ferulic acid, one of the hydroxycinnamic acids distributed widely throughout plant cell walls. Tokyo Chemical Industry supplies it as a non-heterocyclic building block for synthesis laboratories as well as natural product research groups. In the laboratory, the compound serves as a reference material in the analysis of phenolic compounds, as a model substrate in enzyme studies involving feruloyl esterase and lipase, and as a starting material for preparing more lipophilic ferulate derivatives in formulation research.
Several properties make this compound an attractive choice. The molecule combines a phenolic group with a methoxy group at the neighbouring position, a guaiacol motif recognised as an effective free radical scavenger, together with a conjugated acrylate side chain that extends the π electron system. That conjugation produces strong absorption in the ultraviolet region, a property exploited in UV protection research and one that makes detection straightforward with UV detectors in HPLC. Compared with free ferulic acid, the ester form dissolves more readily in organic solvents and organic matrices, which broadens the range of reaction and formulation conditions in which it can be used.
In Indonesian laboratories, this material is typically found in university and institutional research groups working on natural product chemistry, phenolic compound analysis, and cosmetic or pharmaceutical formulation development. It is a practical fit wherever a well-characterised hydroxycinnamate reference or a lipophilic ferulate precursor is required, and it supports both routine analytical comparison work and exploratory synthesis on a bench scale.
Laboratory Applications
Phenolic compound analysis — serves as a comparison and reference material during the identification and quantification of phenolic constituents, with its strong ultraviolet absorption making it readily detectable by UV detectors on HPLC systems.
Enzyme activity studies — functions as a model substrate for ester-hydrolysing enzymes such as feruloyl esterase and lipase, since the ethyl ester linkage provides a defined, cleavable bond suitable for following enzymatic reactions.
Synthesis of ferulate derivatives — acts as a starting material for preparing more lipophilic ferulate compounds, giving formulation researchers a reactive, non-heterocyclic building block with both phenolic and conjugated acrylate handles available.
Ultraviolet protection research — the extended conjugation across the acrylate side chain and aromatic ring gives strong ultraviolet-region absorption, making this compound relevant to laboratory investigations of UV-absorbing and photoprotective materials.
Antioxidant and radical scavenging studies — the guaiacol motif, pairing a phenolic hydroxyl with an adjacent methoxy group, is a recognised effective free radical scavenger and supports comparative antioxidant evaluation work.

Handling and Storage
Store the container in a cool, dry, well-ventilated area away from direct sunlight and other light sources, since the conjugated system in this molecule absorbs ultraviolet light. Keep the material in its original tightly closed container, or transfer it to an amber glass bottle with a chemically resistant closure to limit light and moisture exposure. Handle the compound inside a fume hood using safety glasses, gloves, and a laboratory coat, and avoid generating dust during weighing. Keep it separated from strong oxidising agents, strong acids, and strong bases. Always consult the manufacturer's safety data sheet before opening a new container, and dispose of residues and contaminated materials through your institution's chemical waste procedures.
