FAQ

What are the physical and chemical properties of Xylene cyanol ff (CAS: 2650-17-1)?

Xylene cyanol ff (CAS: 2650-17-1) is a crystalline compound with a molecular weight of approximately 410.27 g/mol. It is sparingly soluble in water but highly soluble in organic solvents. Chemically, it is relatively stable but can undergo hydrolysis under acidic conditions. It is used as a pH indicator and has a deep blue color in alkaline solutions and a light blue color in neutral or acidic solutions.

How is Xylene cyanol ff (CAS: 2650-17-1) typically synthesized?

Xylene cyanol ff (CAS: 2650-17-1) is synthesized through a multi-step process involving the coupling of 2,6-dimethylphenol with 2,6-dimethyl-4-nitroaniline. The reaction is typically performed in the presence of a base and a coupling agent, followed by reduction and subsequent dyeing steps. The overall yield is around 70-80%, and the process requires careful control of pH and temperature to ensure selectivity and yield.

What industries use Xylene cyanol ff (CAS: 2650-17-1)?

Xylene cyanol ff (CAS: 2650-17-1) is primarily used in the textile industry as a pH indicator in dyeing processes. It is also utilized in the food industry as a colorant, particularly in the production of jams, marmalades, and other food products. Additionally, it is used in the pharmaceutical industry for quality control and in analytical chemistry for pH determination in solutions.

What precautions should be taken when handling Xylene cyanol ff (CAS: 2650-17-1)?

When handling Xylene cyanol ff (CAS: 2650-17-1), it is essential to wear proper personal protective equipment (PPE), including gloves and safety goggles. Store the compound in a cool, dry place away from direct sunlight and heat sources. Use a fume hood during preparation and use to minimize inhalation risks. In case of spillage, immediately clean up the area and follow safety protocol outlined in the Material Safety Data Sheet (MSDS/SDS).
