Description

2,3,4-Trimethylvaleraldehyde is a branched-chain aliphatic aldehyde with the CAS number 3601-65-8. This compound serves as a valuable intermediate and building block in organic synthesis, prized for its ability to introduce a specific, sterically hindered alkyl chain. It is primarily sought after by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty fragrance industries for the development of novel active ingredients and complex molecules.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs), particularly where a multi-methylated pentyl moiety is required for biological activity or metabolic stability.
• Agrochemical Synthesis: Serves as a key precursor in the manufacture of herbicides, fungicides, and pesticides, contributing to the lipophilic character of the final product.
• Flavor & Fragrance Ingredient: Acts as a starting material for creating unique aldehydic and alcohol notes in high-value perfumery and flavor compositions.
• Organic Synthesis Building Block: Employed in Grignard reactions, reductive amination, and condensation reactions to construct more complex molecular architectures in research and development.
• Ligand and Catalyst Development: Useful for synthesizing specialized chiral or sterically demanding ligands used in asymmetric catalysis.
• Polymer Modification: Can be utilized to introduce aldehyde functional groups into polymers for subsequent cross-linking or grafting reactions.

Storage

Preserve in a tightly closed container, protected from light. Due to its property of being easily oxidized, this material should be stored under an inert atmosphere (e.g., nitrogen or argon) when in partially used containers. Recommended storage temperature is 2-8°C for long-term stability. Keep away from heat, sparks, and open flames.
