TCI D1368 (1,2-Dimethylpropyl)benzene, CAS 4481-30-5, is an aromatic hydrocarbon consisting of a benzene ring bearing a branched alkyl side chain in the form of a 1,2-dimethylpropyl group. The compound belongs to the non-heterocyclic building block class and represents the group of branched alkylbenzenes that are important in the study of hydrocarbon chemistry. In the laboratory, materials of this kind are used as reference compounds for instrumental analysis, as test substances in aromatic reaction studies, and as structural models when researchers examine how side-chain branching influences the reactivity and physical properties of aromatic molecules.
The properties that make this compound a preferred choice are the stability of its aromatic ring combined with a branched side chain that introduces a distinctive degree of steric hindrance. This combination produces behaviour that differs from that of straight-chain alkylbenzenes, whether in aromatic substitution reactions, side-chain oxidation, or chromatographic retention time. Because the molecule contains no polar functional groups, it is nonpolar in character and yields clean analytical peaks. Reagent-grade purity is decisive when the material is used as a comparison standard, since the presence of other isomers can obscure interpretation of the resulting data.
In Indonesian laboratories, this type of branched alkylbenzene is typically handled within organic chemistry and hydrocarbon analysis work, both in university research groups and in industrial testing units. It commonly appears in method development for chromatographic separation, in structure–reactivity teaching and investigation, and in comparative studies of aromatic side-chain behaviour. Because it is supplied as a defined building block from an established reagent brand, it fits routine workflows where a consistent, well-characterised aromatic reference material is required.
- Chromatographic reference standard — its nonpolar character and absence of polar functional groups give clean, well-defined analytical peaks, making retention time comparison straightforward during method development.
- Aromatic substitution reaction studies — the stable benzene ring combined with a sterically hindered branched side chain allows researchers to observe substitution behaviour that differs from straight-chain alkylbenzene analogues.
- Side-chain oxidation investigations — the 1,2-dimethylpropyl group provides a branched aliphatic target whose oxidation behaviour can be contrasted directly against linear alkyl side chains on aromatic rings.
- Structure–reactivity model compound — it serves as a structural model when examining how side-chain branching influences the reactivity and physical properties of aromatic molecules under controlled laboratory conditions.
- Non-heterocyclic building block in synthesis — as a defined branched alkylbenzene building block, it supports preparative organic chemistry work requiring a hydrocarbon framework without heteroatom interference.

Store the container tightly closed in a cool, dry, well-ventilated area, away from heat, open flames, sparks, and direct sunlight, and separated from strong oxidising agents. Keep the material in its original manufacturer packaging or in a compatible, clearly labelled, tightly sealed glass container so that reagent-grade purity is preserved and contamination by other isomers is avoided. Handle in a fume hood, wear safety goggles, chemical-resistant gloves, and a laboratory coat, and avoid inhalation of vapour or contact with skin and eyes. Always consult the manufacturer's safety data sheet before use, and dispose of residues and contaminated materials through the laboratory's chemical waste procedures.
