Description

2-Methylpropanal is a versatile and highly reactive C4 aldehyde, also known as isobutyraldehyde, with the CAS number 78-84-2. It serves as a critical building block in organic synthesis, valued for its ability to introduce the isobutyl group and undergo various condensation and oxidation reactions. This chemical is essential for manufacturers in the fragrance, agrochemical, pharmaceutical, and polymer industries seeking reliable, high-purity intermediates for their production processes.

Application

• Fragrance and Flavor Intermediates: A key precursor for synthesizing isobutyric acid and its esters, which are widely used in fruit flavors and perfumery.
• Pharmaceutical Synthesis: Employed as a chiral building block and intermediate in the manufacture of various active pharmaceutical ingredients (APIs) and vitamins.
• Agrochemical Production: Used in the synthesis of herbicides, pesticides, and plant growth regulators.
• Polymer and Resin Industry: Acts as a monomer or co-monomer in the production of specialty polymers, coatings, and resins.
• Organic Synthesis: Utilized in aldol condensations, Grignard reactions, and reductive amination to create more complex molecules.
• Solvent and Extraction Agent: Finds application as a selective solvent in certain chemical processes and extraction procedures.

Quality Control

Our 2-Methylpropanal is produced under stringent quality management systems. Every batch undergoes comprehensive analytical testing, including gas chromatography (GC), to ensure high purity and consistency. We provide detailed Certificates of Analysis (COA) with each shipment, confirming compliance with agreed specifications. Our quality commitment supports applications requiring reliable and traceable raw materials.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong oxidizing agents, strong bases, and strong reducing agents. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep container tightly sealed when not in use to prevent evaporation and moisture absorption.
