Description

4,5-Dimethyl-3-Hydroxy-2,5-Dihydrofuran-2-One is a high-purity lactone derivative with a distinct furanone structure, serving as a versatile intermediate and flavor/fragrance component. Its value lies in its ability to impart creamy, caramelic, and nutty flavor notes, making it essential for creating complex sensory profiles. This compound is primarily needed by flavor and fragrance manufacturers, as well as research institutions developing new synthetic pathways for fine chemicals and pharmaceutical intermediates.

Application

• Flavor & Fragrance Industry: A key building block for synthesizing high-value flavor compounds, contributing creamy, buttery, and caramel-like notes to food, beverage, and confectionery products.
• Aroma Chemical Synthesis: Used as a precursor in the production of sophisticated aroma molecules for perfumery, personal care, and household products.
• Pharmaceutical Intermediates: Serves as a chiral synthon in the research and development of active pharmaceutical ingredients (APIs) and other bioactive molecules.
• Fine Chemical Research: Employed in organic synthesis laboratories for studying cyclization reactions and developing novel heterocyclic compounds.
• Food Technology: Potential use in creating natural-identical flavor enhancers and process flavorings for savory and sweet applications.

Quality Control

Our 4,5-Dimethyl-3-Hydroxy-2,5-Dihydrofuran-2-One is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and composition. A comprehensive Certificate of Analysis (COA) is provided with every shipment, detailing results from HPLC, GC, and other relevant analytical methods to guarantee consistency and reliability for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from heat, sparks, and open flame.
