Isovaleraldehyde, identified by its CAS number 590-86-3, is a colorless liquid aldehyde that plays a crucial role across various industrial sectors. Also known as 3-methylbutanal, this compound is characterized by its relatively low boiling point and its distinct, often fruity, aroma. For procurement professionals and researchers in fields such as pharmaceuticals, agrochemicals, and the flavor and fragrance industries, understanding the properties and sourcing channels for Isovaleraldehyde is essential for successful project execution. This guide aims to provide clarity on both aspects.

Chemically, Isovaleraldehyde has the molecular formula C5H10O and a molecular weight of approximately 86.15 g/mol. Its density is around 0.792 g/cm³, and its boiling point is approximately 93.5 °C. It exhibits solubility in water to a limited extent but is readily soluble in common organic solvents like alcohol and ether. These physical and chemical properties make it a versatile reactant in numerous organic synthesis pathways. For instance, its aldehyde group readily participates in nucleophilic addition reactions, aldol condensations, and oxidation/reduction processes.

The primary applications of Isovaleraldehyde stem from its reactivity and aromatic qualities. As previously discussed, it's a vital intermediate in the synthesis of pharmaceuticals and agrochemicals, contributing to the creation of complex active ingredients. In the flavor and fragrance sectors, its fruity scent profile is highly valued. Beyond these core areas, it can also find applications in the production of certain polymers and resins, or as a specialized solvent in specific chemical processes. When seeking to buy this chemical, understanding its intended application helps in specifying the required purity and grade.

When it comes to sourcing Isovaleraldehyde, efficiency and reliability are key. Buyers typically look for direct manufacturers or established suppliers to ensure competitive price and consistent quality. China is a significant global hub for the production of fine chemicals, including Isovaleraldehyde. Companies looking to procure this compound from China often benefit from the scale of production, which can lead to more attractive pricing, especially for bulk orders. However, it is imperative to vet potential suppliers thoroughly, checking for certifications, quality control processes, and their ability to provide comprehensive documentation such as Certificates of Analysis (COA) and Safety Data Sheets (SDS).

The process of placing a purchase order for Isovaleraldehyde usually involves requesting a quote based on the required quantity and specifications. Reputable suppliers will provide detailed product information, including purity, CAS number, and any relevant regulatory compliance data. Shipping and logistics are also critical considerations, especially for international transactions. Understanding Incoterms and potential import regulations ensures a smooth transaction and timely delivery of the product to your facility.

In conclusion, Isovaleraldehyde (CAS 590-86-3) is a fundamental organic intermediate with diverse industrial applications. By understanding its chemical properties and diligently evaluating sourcing options from reliable manufacturers and suppliers, businesses can ensure they obtain this essential compound effectively and economically, supporting their ongoing research and production needs.
