Properties of UV Absorber Tiangang® UV-570

UV absorbers play an important role in modern chemical and medical fields. As a key auxiliary, they are widely used across many domains. Among them, UV-570 is an organic compound with strong UV absorption and degradation durability; its development and application open up unlimited possibilities for modern technological progress and industrial production. This article introduces the preparation, properties, and applications of UV-570.

1. Preparation of UV-570

UV-570 is a heterocyclic compound developed by Germany's BASF; its structural formula is C35H49N3O2. Its preparation mainly involves the following steps:

(1) Using L-tyrosine as the raw material, N-(2-hydroxyethyl)-L-tyrosine ethyl ester (HECA) is synthesized via amination and thermal condensation reactions.

(2) HECA is condensed with benzoic acid to yield a heterocyclic compound.

(3) Pure UV-570 is obtained after refinement.

Through this preparation process, the product is obtained as a pale-yellow crystal; its chemical structure is shown in Figure 1.
