Product Name: 4-Fluorophenylacetone CAS No.: 459-30-0 Molecular weight:52.16     Molecular formula: C9H9FO Package:10G/100G/25KG     Appearance: Yellow Liquid Synonyms:(4-Fluorophenyl)acetone/ 1-(4-fluorophenyl)propan-2-one /4- Fluorophenylacetone Description T , his intermediate, also known as (4-Fluorophenyl)acetone, presents as a dark yellow liquid.  It is known to be insoluble in water. For best results, store in a tightly closed container in a dry and well-ventilated place.  Containers that are opened must be carefully resealed and kept upright to prevent leakage.  4-Fluorophenylacetone is incompatible with strong oxidizing agents. This chemical is a combustible liquid. Chemical Properties clear yellow liquid Uses 4-Fluorophenylacetone is an important raw material and intermediate used in organic synthesis, pharmaceuticals, agrochemicals, and dyestuff fields.  It is a haloarylacetone derivative used in a study of reversed enantiopreference of an ω-transaminase by a single-point mutation. Application (4-Fluorophenyl)ac , etone is a phenylacetic acid derivative that inhibits the 5-HT2 receptors.  It has been shown to have inhibitory activities against dopamine and serotonin by acting as an agonist at the receptor.  (4-Fluorophenyl)acetone also binds to nucleophilic sites on proteins, which may lead to inhibition of protein synthesis.  Brevibacterium sp. strain P7 was used as a model system and it was found that it inhibited the growth of this bacterium by binding to the enzyme RNA polymerase, preventing transcription and replication.
