Key Properties
Sodium pentachlorophenate (extra pure, sentobrite) is a heavily chlorinated phenolate that has been historically utilized as a wood preservative and herbicide. This compound is notable for its high degree of chlorination, which contributes to its effectiveness in preventing decay and pest damage in wood products. With a purity of 80%, it is classified as extra pure, making it suitable for specialized applications in research and analysis. The compound's molecular weight is 288.32 g/mol, and it is recognized by its CAS number 131-52-2, which is essential for regulatory and safety documentation.
Also known as Sentobrite.
