Description

2-Methylbutyraldehyde is a versatile, short-chain aliphatic aldehyde with a characteristic pungent, fruity odor. This compound serves as a crucial building block and flavor/fragrance intermediate in various high-value chemical syntheses. It is primarily utilized by manufacturers in the flavor & fragrance, pharmaceutical, and agrochemical industries for producing esters, alcohols, and other derivatives.

Application

• Flavor and Fragrance (F&F) Industry: A key intermediate for synthesizing fruity and nutty flavor compounds (e.g., 2-Methylbutyric acid, corresponding esters) used in food, beverages, and perfumery.
• Pharmaceutical Intermediates: Serves as a chiral building block in the synthesis of active pharmaceutical ingredients (APIs) and other fine chemicals.
• Agrochemical Synthesis: Used in the production of pesticides, herbicides, and plant growth regulators.
• Resin and Polymer Modification: Acts as a modifier or cross-linking agent in specialty polymer formulations.
• Organic Synthesis: A valuable reagent in aldol condensations, Grignard reactions, and reductive amination for producing more complex molecules.
• Solvent and Extraction Aid: Employed in specific niche extraction and purification processes.

Quality Control

Our 2-Methylbutyraldehyde is produced under stringent quality management systems. Every batch undergoes rigorous analytical testing to ensure it meets high-purity standards and consistent specifications for critical parameters such as assay, identity, and impurity profiles. A comprehensive Certificate of Analysis (COA) is provided with each shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flame. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) and keep the container tightly sealed when not in use. Recommended storage temperature: 2-8°C (cold chain) for extended stability, or at controlled room temperature for short-term use.
