Uses

Approximately 50% of synthetic catechol (CAS NO.120-80-9) is consumed in the production of pesticides, the remainder being used as a precursor to fine chemicals such as perfumes and pharmaceuticals. Catechol (CAS NO.120-80-9) is a common building block in organic synthesis. Several industrially significant flavors and fragrances are prepared starting from Catechol (CAS NO.120-80-9).
