CAS 17540-75-9: 2,6-Di-tert-butyl-4-sec-butylphenol

Description:2,6-Di-tert-butyl-4-sec-butylphenol, with the CAS number 17540-75-9, is an organic compound that belongs to the class of phenolic antioxidants. It is characterized by its bulky tert-butyl groups at the 2 and 6 positions and a sec-butyl group at the 4 position of the phenolic ring, which contribute to its steric hindrance and stability. This compound is typically a white to light yellow solid at room temperature and is insoluble in water but soluble in organic solvents. It exhibits excellent thermal stability and antioxidant properties, making it useful in various industrial applications, particularly in plastics, rubber, and lubricants, where it helps prevent oxidative degradation. Additionally, it has a relatively high melting point and is known for its low volatility, which enhances its effectiveness as a stabilizer in formulations. Safety data indicates that, while it may pose some health risks, proper handling and usage guidelines can mitigate these concerns.
