Application:
Methyl 4-tert-Butylbenzoate (MPTBBA) (CAS: 26537-19-9) is mainly used for sunscreen agent and p-tert-butyl benzaldehyde, is used as an important intermediate in organic synthesis, used as pharmaceutical / pesticide / cosmetic intermediates. MPTBBA is mainly used for the production of sunscreen agent Avobenzone (CAS: 70356-09-1). Avobenzone is an oil soluble ingredient used in sunscreen products to absorb the full spectrum of UVA rays. It is a dibenzoylmethane derivative. Avobenzone exists in the ground state as a mixture of the enol and keto forms, favoring the chelated enol. Its ability to absorb ultraviolet light over a wider range of wavelengths than many organic sunscreen agents has led to its use in many commercial preparations marketed as "broad spectrum" sunscreens. Avobenzone has an absorption maximu of 357 nm. Methyl 4-tert-Butylbenzoate is an essential intermediate in organic synthesis and an important additive in producing PVC heat stabilizer, PP nucleating agent, sunscreen agent, and flux.
