ETHYL ORANGE(CAS: 13545-67-0)

ETHYL ORANGE is a crystalline compound with a molecular weight of approximately 134.17 g/mol. It has a low solubility in water (0.02 g/100 mL at 20°C) but is soluble in organic solvents like ethanol and dichloromethane. It exhibits a strong electron-withdrawing effect due to its phenolic group, making it moderately reactive in the presence of bases and reducing agents. It is typically used in analytical chemistry and as a reference dye.

ETHYL ORANGE is commonly synthesized via the condensation of phenol and acetylacetone in the presence of a strong base like sodium hydroxide. The reaction involves the formation of a mixed anhydride intermediate, followed by the condensation step. High selectivity and good yield are achieved, with the final product purified by recrystallization from ethanol.

ETHYL ORANGE is used in various industries, including pharmaceuticals for coloration and as an intermediate in the synthesis of other compounds, sensors for detecting specific chemical species, and semiconductors for doping purposes. It is also utilized in polymer science for dyeing and coloring applications.

Handling ETHYL ORANGE requires caution due to its potential skin and eye irritation. It is recommended to wear appropriate personal protective equipment (PPE) including gloves and safety goggles. Work should be conducted in a well-ventilated area or fume hood. Spills should be handled by carefully collecting the material and disposing of it according to local regulations. Refer to the Material Safety Data Sheet (MSDS) for detailed safety information.
