Benzophenone is a chemical compound commonly used as a UV filter in sunscreens and as a flavoring agent in food. The spelling of benzophenone can be tricky due to its silent letter ‘p’ and the combination of letters ‘ph’. The IPA phonetic transcription for benzophenone is /ˌbɛnzoʊˈfiːnoʊn/. This transcription breaks down the word into its individual sounds. The ‘ph’ sound is represented by the symbol /f/ and the silent ‘p’ is not represented at all. By understanding the IPA phonetic transcription, the correct spelling of benzophenone can be easily remembered.
Benzophenone is a noun that refers to a colorless solid compound with a distinctive aroma, typically derived from benzene, that consists of two phenyl groups connected by a carbonyl group. It is also known by its chemical formula C₁₃H₁₀O.
Benzophenone is widely used in various industries, including pharmaceuticals, cosmetics, and plastics. In pharmaceuticals, it is commonly employed as a photoprotective agent to prevent the degradation of sensitive ingredients in medications by harmful ultraviolet (UV) rays. Benzophenone acts as a UV filter by absorbing the UV radiation and converting it into less destructive forms of energy, reducing the risk of product deterioration.
Moreover, benzophenone is extensively utilized in the production of fragrances, especially in the form of synthetic musks. It adds a distinct scent and enhances the longevity of the fragrance when combined with other components. Additionally, this compound is an essential ingredient in the manufacture of plastic materials. It acts as a UV stabilizer, protecting plastics from the damaging effects of prolonged sun exposure, ultimately extending their lifespan.
However, prolonged or excessive exposure to benzophenone can cause harmful effects. Studies have suggested that it may be a potential endocrine disruptor, interfering with hormone function in the body. Therefore, it is important to consider its appropriate and safe usage in different applications while ensuring the well-being of individuals and the environment.
The word "benzophenone" is derived from combining two parts: "benzo" and "phenone".
1. "Benzo" is derived from "benzene", which refers to a hydrocarbon compound consisting of six carbon atoms arranged in a ring. The term "benzene" originated in 1833 from the German word "Benzin", which means "benzine" or "light oil". It was first isolated from coal tar by the British chemist Michael Faraday.
2. "Phenone" refers to a class of organic compounds that contain a carbonyl group (C=O) bonded to a phenyl group (C6H5-). The term "phenone" is derived from the combination of "phenyl" and "ketone".
