Cyclopentanone,2-(2-methylpropyl)-

Description:

Cyclopentanone, 2-(2-methylpropyl)-, also known by its CAS number 4668-65-9, is a cyclic ketone characterized by a five-membered carbon ring with a ketone functional group and a branched alkyl substituent. This compound features a cyclopentanone core, which contributes to its unique chemical properties, including its reactivity and volatility. The presence of the 2-(2-methylpropyl) group introduces steric hindrance and influences the compound's boiling point and solubility. Cyclopentanone derivatives are often used in organic synthesis and can serve as intermediates in the production of various chemicals. The compound is typically a colorless liquid with a characteristic odor, and it is soluble in organic solvents. Its chemical behavior is influenced by the presence of the ketone functional group, making it susceptible to nucleophilic attack and oxidation reactions. Safety considerations should be taken into account when handling this substance, as it may pose health risks if inhaled or ingested.

2-Iso-butylcyclopentanone

CAS: 4668-65-9

2-Iso-butylcyclopentanone is a ketone that has triplet and singlet states with rate constants of 8.9x10 M/s and 0.003 M/s, respectively. It has been shown to undergo photoelimination reactions in the presence of acyclic or cyclic triplet sensitizers. 2-Iso-butylcyclopentanone also undergoes a rate-limiting step in the formation of an excited state, which is called the S1 state or triplet. This reaction can be followed by measuring the fluorescence spectrum of the compound using a spectrofluorimeter, which shows that it emits light at wavelengths of 333 nm and 395 nm.
