TCI T1104 is (E)-3,4,5-Trimethoxycinnamic Acid, registered under CAS number 20329-98-0. It is a cinnamic acid derivative whose aromatic ring carries three methoxy groups at the 3, 4, and 5 positions. The (E) prefix indicates a trans configuration at the carbon-carbon double bond. The compound is classed as a non-heterocyclic building block, and in the laboratory it serves as a starting material for constructing more elaborate organic molecules.

The molecule combines three structural features: a trimethoxyphenyl ring, a conjugated double bond, and a carboxylic acid group. Together they give synthetic chemists several reactive sites to work with. The carboxylic acid can be converted into esters or amides, while the conjugated double bond can be reduced or take part in addition reactions with a range of reagents. This flexibility makes the compound a versatile starting material. Both the cinnamate framework and the trimethoxyphenyl motif are widely studied in medicinal chemistry and natural product research, so the compound is often chosen when building libraries of analogues. For physical properties, including solubility, consult the manufacturer's data sheet before planning solvents and reaction conditions.

In Indonesian laboratories, this compound is relevant to research groups working in organic synthesis, medicinal chemistry, and natural product chemistry, particularly those preparing series of related derivatives from a common scaffold. It suits teams that need a defined, well-characterized building block from an established brand such as TCI. AMI Scientific supplies it for such research and development work.

Ester synthesis: the carboxylic acid group can be converted into a range of esters, so this compound suits research groups that need to prepare series of trimethoxycinnamate derivatives from a single starting material.
Amide synthesis: the same carboxylic acid function can be coupled with amines to form amides, which makes the compound a practical choice for analogue libraries in medicinal chemistry programs.
Reduction of the conjugated double bond: the alkene conjugated to the aromatic ring and the acid group can be reduced, allowing chemists to move from the cinnamate framework to saturated analogues for comparison studies.
Addition reactions: the conjugated double bond can react with various addition reagents, so the compound is suitable for exploring how this structural unit behaves in new synthetic routes.
Natural product and medicinal chemistry research: the cinnamate scaffold and the trimethoxyphenyl motif both appear frequently in these fields, which makes the compound a convenient starting point for building related structures.
