TCI T1101 is 2,3,4-Trimethoxybenzaldehyde, registered under CAS number 2103-57-3. It is an aromatic compound, a benzaldehyde that carries three methoxy groups at positions 2, 3, and 4 of the ring. The material belongs to the non-heterocyclic building block category, meaning it is a starting material used to assemble more complex organic molecules. Its main role in the laboratory is to supply a reactive aldehyde group together with a trimethoxyphenyl ring that has a defined substitution pattern, which makes it a practical entry point for the synthesis of many aromatic derivatives.

The aldehyde group of this compound can undergo many classical transformations, including condensation, reduction, oxidation, and reductive amination. The three methoxy groups influence the electron density of the ring and therefore shape the character of the final products. The 2,3,4 substitution pattern differs from the more commonly encountered 3,4,5 isomer, so this compound is chosen when the target framework specifically requires that arrangement of methoxy groups. Detailed physical properties should be taken from the manufacturer's data sheet rather than assumed from a related isomer, and this reference should be followed when planning reactions.

In Indonesian laboratories, this reagent is relevant to researchers working in organic synthesis, medicinal chemistry, and natural product chemistry who are preparing analogues of aromatic compounds. It is typically used in small research-scale quantities, where a clearly identified starting material with a traceable CAS number simplifies method development and documentation. AMI Scientific supplies this TCI product to laboratories that need a dependable building block for synthetic programs, teaching laboratories, and exploratory research projects across the country.

  • Synthesis of aromatic derivatives: the reactive aldehyde group and the trimethoxyphenyl ring make this compound a convenient starting point for building a wide range of substituted aromatic molecules.
  • Condensation reactions: the aldehyde function readily takes part in classical condensation chemistry, which suits researchers who need to extend the carbon skeleton from a defined 2,3,4-trimethoxyphenyl unit.
  • Reductive amination: converting the aldehyde into amine-bearing products is a common route, and this building block provides the specific methoxy substitution pattern required for such target structures.
  • Medicinal chemistry analogue preparation: medicinal chemists can use it to prepare analogues of aromatic compounds where the 2,3,4 arrangement of methoxy groups is deliberately needed in the target framework.
  • Natural product chemistry studies: researchers working on natural product related structures can use this reagent as a source of the trimethoxyphenyl ring when constructing or modifying aromatic compounds.

Store the container tightly closed in a cool, dry, well-ventilated place, away from direct sunlight, heat sources, and incompatible materials such as strong oxidizing agents. Because it is an aldehyde, it is best kept in its original manufacturer container, or in a clean, tightly sealed glass bottle, to limit contact with air and moisture. Always confirm the exact storage conditions on the manufacturer's label and safety data sheet. During use, wear standard laboratory protective equipment, including gloves, safety glasses, and a lab coat, and handle the material in a fume hood or well-ventilated area. Avoid inhalation, skin contact, and ingestion, and label any secondary containers clearly. Dispose of waste in accordance with your institution's chemical waste procedures.
