Description

Description générale

1,4-Diisocyanatobutane is a highly reactive compound with two isocyanate (-NCO) groups separated by a butane chain. It can undergo reactions such as urethane formation, crosslinking, and chain extension. It is widely used as a building block to synthesize polyurethane-based materials with excellent flexibility, impact resistance, and mechanical properties, making them useful in tissue engineering, contact lenses, biocompatible coatings, adhesives, foams, elastomers, and sealants.

Application

1,4-Diisocyanatobutanecan be used in the following fields:

Tissue engineering -As a precursor to synthesize polyurethane composites which can be used as 3D scaffolds for tissue engineering,

Contact lenses- As a cross-linking agent to prepare inorganic-organic hydrogel contact lenses for high refractive index ocular refractive correction biomaterial,

Controlled drug delivery- As a chain extender to synthesize segmented polyurethanes for redox-sensitive controlled drug release systems.
