For any chemical professional involved in synthesis or procurement, a deep understanding of a compound's properties is fundamental to its successful application. Dimethyl Malonate (CAS 108-59-8), a di-ester of malonic acid, possesses a unique set of characteristics that make it invaluable across various chemical industries. Exploring these properties helps explain why it is a sought-after intermediate and what to look for when you buy.

Physically, Dimethyl Malonate presents as a clear, colorless liquid. Its low melting point of -62 °C means it remains liquid even at significantly sub-zero temperatures, facilitating handling and processing in diverse laboratory and industrial environments. Its boiling point is approximately 180-181 °C, indicating a moderate volatility. The density is around 1.156 g/mL at 25 °C, which is slightly heavier than water. These physical attributes are critical for formulators and process engineers when designing reaction conditions and storage protocols.

Chemically, Dimethyl Malonate's reactivity stems from the active methylene group situated between the two carbonyl functionalities. This feature allows it to readily undergo alkylation, acylation, and condensation reactions. This inherent reactivity is what makes it such a versatile building block. For example, in organic synthesis, it acts as a crucial synthon for introducing a three-carbon fragment with functionalizable termini. The ability to buy Dimethyl Malonate with high purity ensures that these reactions proceed efficiently and with predictable outcomes.

Solubility is another key property. Dimethyl Malonate is miscible with common organic solvents such as alcohol, ether, and oils, but only slightly miscible with water. This differential solubility can be exploited in separation and purification processes. When considering a purchase, procurement specialists often look for manufacturers that guarantee a minimum purity level, often 98% or 99%, to ensure consistent performance in sensitive syntheses.

The availability of Dimethyl Malonate from reliable suppliers and manufacturers, particularly those in China, ensures that these essential properties are accessible to the global market. Understanding these chemical and physical aspects allows researchers and purchasing managers to make informed decisions, ensuring they select the appropriate grade and quantity for their specific synthesis needs.
