The product we are introducing here is high - quality benzil with the CAS number 134 - 81 - 6. Benzil is an organic compound with the chemical formula C₁₄H₁₀O₂. It is a yellow crystalline solid at room temperature. The high - quality aspect of this product ensures its purity, which is crucial for various applications. The low price makes it an attractive option for both small - scale laboratory experiments and large - scale industrial productions.
Some key physical and chemical parameters include a melting point around 94 - 96 °C and a boiling point of approximately 346 - 348 °C. It is sparingly soluble in water but soluble in common organic solvents such as ethanol, ether, and chloroform. This solubility property plays an important role in its usage in different chemical reactions.
Benzil has a wide range of applications in different fields. In the field of organic synthesis, it serves as a key intermediate. For example, it can be used in the preparation of various heterocyclic compounds. These heterocyclic compounds are of great significance in the pharmaceutical industry, as many drugs contain heterocyclic structures.
It is also used in the manufacturing of dyes. Benzil can participate in chemical reactions to form colored compounds, which can be used as dyes for textiles and other materials. In the field of analytical chemistry, benzil can be used as a reagent for the detection and determination of certain metal ions. Its specific chemical properties allow it to form complexes with metal ions, resulting in color changes or other detectable signals.
When using benzil, first, ensure that you are working in a well - ventilated area, as it is an organic compound and some of its vapors may be harmful if inhaled in large quantities. Wear appropriate personal protective equipment, such as gloves and safety glasses.
If you are using it in an organic synthesis reaction, accurately weigh the required amount of benzil according to the reaction stoichiometry. Dissolve it in a suitable organic solvent, and then add other reactants gradually under controlled temperature and reaction conditions. Stir the reaction mixture continuously to ensure uniform reaction. After the reaction is complete, follow the appropriate separation and purification procedures to obtain the desired product.
If it is used as a reagent in analytical chemistry, prepare a standard solution of benzil with a known concentration. Add the sample solution containing the target metal ions to the benzil solution. Observe the color change or other signals, and then compare the results with the standard curves to determine the concentration of the metal ions in the sample.
Caso 1: Síntese farmacêutica
A pharmaceutical research company was developing a new anti - inflammatory drug. They used benzil as an intermediate in the synthesis of a key heterocyclic compound. First, they dissolved benzil in ethanol at a temperature of about 50 °C. Then, they added a specific amine compound and a catalytic amount of acid. The reaction was carried out under reflux conditions for about 6 hours. After the reaction, they used column chromatography to purify the product. The yield of the heterocyclic compound was about 75%. This heterocyclic compound was further used in the subsequent steps of drug synthesis, and the final anti - inflammatory drug showed good activity in pre - clinical trials.
Case 2: Dye Manufacturing
A textile dyeing factory wanted to develop a new yellow dye. They used benzil as one of the raw materials. They reacted benzil with a specific aromatic compound in the presence of a base catalyst in a solvent mixture of chloroform and water. The reaction was carried out at a temperature of 60 - 70 °C for 8 hours. After the reaction, they isolated the dye by precipitation and filtration. The dye was tested on cotton fabrics, and it showed good color fastness and bright yellow color, meeting the factory's requirements for textile dyes.
