Description

Application

Trimethyl 4-bromoorthobutyrate was used in the synthesis of macrocyclic lactone (S)-curvularin. Grignard reagent derived from trimethyl 4-bromoorthobutyrate was used in the preparation of novel hapten 4-(17 β-hydroxy-3-oxoestra-4,9-dien-11-β-yl)butanoic acid, used in enzyme-linked immunosorbent assay (ELISA) for testosterone.
