TCI T1092 is Methyl 3,4,5-Trimethoxybenzoate (CAS 1916-07-0), the methyl ester of benzoic acid carrying three methoxy groups at the 3, 4, and 5 positions of the aromatic ring. The trimethoxyphenyl motif appears frequently in bioactive molecules and natural products. In the laboratory, this compound is used as a non-heterocyclic building block that is relatively stable and easy to modify at its ester group, allowing chemists to convert it into alcohols, aldehydes, acids, or amides as a synthesis requires.

Researchers choose this compound for its good stability and its ease of transformation. The methyl ester group can be reduced to a benzylic alcohol, hydrolyzed to the free acid, or converted into amides and hydrazides. The three methoxy groups give the aromatic ring an electron-rich character with a symmetrical substitution pattern. That symmetry simplifies the interpretation of NMR spectra, and the pattern is often desired in the scaffolds of pharmacologically relevant compounds. These features make the material a practical starting point for multistep routes where predictable behavior matters.

In Indonesian laboratories, Methyl 3,4,5-Trimethoxybenzoate suits research groups working in organic synthesis, natural product chemistry, and medicinal chemistry. Pack sizes of 25 g and 500 g are available, covering small-scale research as well as larger staged syntheses. Researchers can use it as a starting material for building trimethoxyphenyl derivatives, and as a reference substrate when developing or checking reaction conditions for aromatic esters in teaching and research settings.

Organic synthesis starting material: the stable methyl ester and the electron-rich trimethoxy ring let chemists build more complex molecules in several steps with predictable behavior at each stage.
Reduction to benzylic alcohol: the methyl ester group can be reduced to the corresponding benzylic alcohol, which makes this compound a convenient entry point to further functionalization of the same aromatic framework.
Hydrolysis to the free acid: the ester can be hydrolyzed to give the free carboxylic acid, so laboratories can obtain the acid form directly from a stable, easily handled ester precursor when needed.
Amide and hydrazide preparation: the ester group can be converted into amides and hydrazides, giving a simple route to derivatives for medicinal chemistry programs that explore trimethoxyphenyl-based structures.
NMR interpretation and teaching: the symmetrical 3,4,5-substitution pattern simplifies spectra, which helps students and researchers interpret aromatic substitution and verify reaction outcomes in natural product and synthesis work.
