p-Cymene

Description:
p-Cymene, also known as para-cymene, is an aromatic hydrocarbon with the chemical formula C10H14. It is a colorless liquid with a pleasant, citrus-like odor, commonly found in essential oils, particularly in thyme and cumin. p-Cymene is characterized by its low solubility in water but high solubility in organic solvents, making it useful in various applications. It has a boiling point of approximately 176 °C and a melting point around -48 °C. This compound is known for its antimicrobial and antioxidant properties, which contribute to its use in food preservation and cosmetics. Additionally, p-cymene is utilized as a solvent in chemical reactions and as an intermediate in the synthesis of other organic compounds. Its structure features a methyl group and an isopropyl group attached to a benzene ring, contributing to its reactivity and versatility in organic chemistry. Safety data indicates that while p-cymene is generally regarded as safe in low concentrations, it should be handled with care due to potential irritant effects.
