| Aspect | Details |
|---|---|
| Chemical Name | 2.3.4.5-Tetramethyl-2-Cyclopentanone |
| Other Names | None widely recognized alternative names |
| CAS Number | 54458-61-6 |
| Molecular Formula | C₉H₁₆O |
| Molecular Weight | 140.22 g/mol |
| Physical State | Likely a colorless to pale yellow liquid (based on similar cyclopentanone derivatives) |
| Melting Point | Not well-documented; estimated to be in the range of -20°C to 0°C (-4°F to 32°F) based on structural considerations |
| Boiling Point | Not well-documented; estimated to be around 180 – 200°C (356 – 392°F) due to its molecular structure and size |
| Density | Not well-documented; expected to be slightly higher than water (around 0.9 – 1.0 g/cm³) due to its non-polar nature |
| Solubility | Expected to be soluble in organic solvents such as ethanol, ether, and benzene. Poorly soluble in water due to its non-polar nature |
| Synthesis Method | Can be synthesized through the reaction of 2.3.4.5-tetramethylcyclopentadiene with an oxidizing agent such as potassium permanganate in an acidic medium |
| Applications | Used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals, fragrances, and specialty chemicals |
| Safety Precautions | Handle with appropriate protective equipment due to potential irritation and flammability risks |
