Urea (Carbamide, CH4N2O) is a versatile nitrogen-based compound with wide applications:
-Textile/Dyeing: Enhances dye solubility, reduces wastewater load in printing (replaces excess urea via pre-wetting techniques).
-Leather: Softens hides and retains moisture during tanning.
-Construction: Acts as a concrete admixture to regulate hardening and reduce cracks.
-AdBlue®: Key component (32.5% solution) for engine NOx reduction.
