For chemists and researchers involved in organic synthesis, a thorough understanding of the physical and chemical properties of key intermediates is fundamental to successful experimentation and production. Dimethyl Methoxymethylenemalonate, identified by CAS number 22398-14-7, is one such compound whose characteristics dictate its utility and handling. When planning to buy Dimethyl Methoxymethylenemalonate, familiarizing yourself with these properties is an essential first step.

The appearance of Dimethyl Methoxymethylenemalonate is typically described as a white to off-white crystalline solid. This physical state is important for material handling, storage, and dissolution in reaction solvents. The melting point, generally reported in the range of 40-44 °C, provides a clear indicator of its purity and physical stability under typical laboratory conditions. A sharp melting point within this range suggests a high-purity product, which is desirable for sensitive synthetic applications. Purchasing from a supplier that provides precise melting point data is advisable.

Chemically, Dimethyl Methoxymethylenemalonate is an ester of malonic acid substituted with a methoxymethylidene group. Its molecular formula is C7H10O5, and its molecular weight is approximately 174.15 g/mol. The presence of the ester groups and the activated double bond makes it highly reactive and amenable to a variety of nucleophilic addition and substitution reactions. This reactivity is precisely what makes it such a valuable building block in complex organic syntheses. When you purchase this compound, understanding its potential reaction pathways is key to its effective utilization.

The boiling point of Dimethyl Methoxymethylenemalonate is often cited under reduced pressure, such as 98 °C at 0.5 mmHg, indicating it can be distilled for purification if necessary, though care must be taken to avoid decomposition at higher temperatures. Its density is estimated around 1.2311, and its refractive index around 1.4390, although these values might vary slightly depending on purity and measurement conditions. These physical parameters are useful for identification and quality control purposes when you buy the material.

Safety information is also critical. Dimethyl Methoxymethylenemalonate is classified with hazard statements such as H301 (Toxic if swallowed), H315 (Causes skin irritation), H319 (Causes serious eye irritation), and H335 (May cause respiratory irritation). Therefore, appropriate handling procedures, including the use of personal protective equipment (PPE) like gloves, safety glasses, and lab coats, are mandatory. Always consult the Safety Data Sheet (SDS) provided by the manufacturer before handling. When seeking to buy Dimethyl Methoxymethylenemalonate, ensure your supplier provides an up-to-date SDS.

In summary, understanding the appearance, melting point, chemical structure, reactivity, and safety profile of Dimethyl Methoxymethylenemalonate is essential for researchers and chemists. By focusing on these properties and sourcing from reliable suppliers who provide detailed technical data, you can ensure the successful and safe application of this important chemical intermediate in your work.
