Beskrivning

CAS: 943-89-5 | C10H10O3 | 178.19 g/mol

Esters derived from trans-4-methoxycinnamic acid are effective absorbers of UV radiation. The starting material was trans-4-methoxycinnamic acid and 3,5dimethoxybenzoic acid methyl ester in isolated avenanthramide alkaloids synthsis. trans-4-Methoxycinnamic acid was converted into its acid chloride (yield 98%) with thionyl chloride. Employed in organic synthesis of pharmaceutical intermediates, synthetic anti-adrenergic drugs esmolol, cosmetics ultraviolet absorption.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand.
