1-(1,1-Dimethylethyl)-3,5-dimethylbenzene

Description:

1-(1,1-Dimethylethyl)-3,5-dimethylbenzene, commonly known as pseudocumene, is an aromatic hydrocarbon characterized by its three methyl groups attached to a benzene ring. The molecular formula for pseudocumene is C10H14, and it features a branched alkyl group, specifically a tert-butyl group, which contributes to its unique properties. This colorless liquid has a sweet, aromatic odor and is insoluble in water but soluble in organic solvents. Pseudocumene is primarily used as a solvent and as an intermediate in the production of various chemicals, including resins and plastics. Its boiling point is relatively high compared to other hydrocarbons, and it exhibits low toxicity, making it suitable for various industrial applications. Additionally, pseudocumene is stable under normal conditions but can undergo combustion, producing carbon dioxide and water. Safety precautions should be taken when handling this substance, as it can be flammable and may cause irritation upon contact with skin or eyes.

Impurity Xylometazoline EP Impurity D
Applications 1-​tert-​Butyl-​3,​5-​dimethylbenzene (Xylometazoline EP Impurity D) is a reagent used in the synthesis of polyarenes as oligonapthalene derivatives as well as in the preparation of arylsulfur trifluorides from diaryl disulfides. Xylometazoline derivative, a vasoconstrictor involved in signal transduction, also used as a nasal decongestant. May be used in treatments involving ischemic injury due to the ability to shift energy metabolism from mitochondrial to glycolysis (2).
