This article explores its key characteristics, synthesis pathways, and the broad spectrum of its industrial applications, highlighting why sourcing this material from reputable manufacturers is crucial.

Chemical Properties and Stability

Esterdiol 204 presents as a white to almost white powder or crystalline solid, with a melting point typically ranging between 46-50°C. Its boiling point is approximately 292°C, and it exhibits a density of 1.01 g/cm³. A notable feature is its solubility in methanol, appearing almost transparent, indicating good compatibility with polar organic solvents. The compound's quaternary structure is a significant contributor to the exceptional stability of its derivatives. This inherent stability is a critical factor for its use in applications where longevity and resistance to degradation are essential. The hydroxyl groups present also allow for standard reactions of primary alcohols, offering further synthetic versatility for B2B clients.

Synthesis and Purity Considerations

The production of Esterdiol 204 can be achieved through several methods. A common route involves a Tishchenko reaction directly from hydroxypivaldehyde in the presence of a basic catalyst, such as aluminum oxide. Alternatively, it can be synthesized via the esterification of neopentyl glycol with hydroxypivalic acid. Achieving high purity, essential for many advanced applications, is typically accomplished through subsequent distillation. For procurement managers and R&D scientists, understanding these synthesis routes and the importance of purity is key to selecting the right supplier. Ensuring a consistent supply of high-purity material directly impacts the quality of the end product.
