Butyl levulinate

Butyl levulinate (CAS 2052-15-5) is an ester derived from levulinic acid, commercially known under trade names including NS 200, NXT Solv 200, and NBL, and registered under FEMA 2207. It carries no E-code designation. The compound belongs to the organic acids category and is classified under HS code 29183000.

In food and flavour applications, butyl levulinate functions as a flavouring agent, contributing fruity and caramel-like notes at controlled concentrations. As an industrial solvent, it dissolves resins and polymer coatings through its moderate polarity and low volatility profile. In plastics formulations, it acts as a plasticizer by intercalating between polymer chains to reduce brittleness and improve flexibility.

Butyl levulinate is supplied in compliance with REACH regulations and is available in food-grade quality aligned with FEMA 2207 specifications. It is offered as a clear liquid in standard industrial packaging formats. Procurement teams should confirm grade suitability against FCC or internal quality standards prior to use.
