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
