English name: Cyanuric fluoride CAS:675-14-9 EINECS: No. 211-620-8 MDL number: MFCD00014597 Molecular weight:135.05 Appearance: colorless liquid. Boiling point: 69.5-70.5℃. Melting point: -38°C Boiling point: 73-74°C Density: 1,6 g/cm3 Refractive index: 1.348 Flash point: 73-74°C Solubility: soluble in chloroform, carbon tetrachloride, ether, dioxane and miscible in ketones. Decomposes violently when exposed to water and alcohol. Acidity coefficient (pKa): -2.62±0.10 (Predicted) Sensitivity: Moisture sensitive BRN: 124237 Use 1: Mainly used to prepare reactive dyes Use two: used in organic synthesis. Overview: Cyanuric fluoride is a key intermediate in the synthesis of fluorinated s-triazine reactive dyes. Compared with traditional chlorotriazine reactive dyes, fluorinated s-triazine reactive dyes have the following five advantages: 1. Energy saving, low dyeing temperature (medium temperature type) 60℃, lower than KE type reactive dyes and equivalent to M type reactive dyes. 2. Emission reduction, environmental protection, and high color fixation rate. The color fixation rate is 15 to 20 percentage points higher than that of the corresponding chlorotriazine reactive dyes. It can not only improve the utilization rate of dyes, but also reduce environmental pollution during the printing and dyeing process. 3. The dye has good stability. 4. High peroxide resistance and stability. 5. Not restricted by AOX regulations.

Product Name: 4-Fluorophenylacetone CAS No.: 459-30-0 Molecular weight:52.16 Molecular formula:C9H9FO Package:10G/100G/25KG Apparence: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 which 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 has found that it inhibited the growth of this bacterium by binding to the enzyme RNA polymerase, preventing transcription and replication.
