3-Methyl-1,5-Pentanediol (3-MPD), identified by CAS No. 4457-71-0, stands as a premier chemical intermediate offered by NINGBO INNO PHARMCHEM CO.,LTD. This highly versatile diol is a colorless liquid, distinguished by its exceptional purity of 98.0% or greater, making it a critical component across diverse industrial applications. With a molecular formula of C6H14O2 and a molecular weight of 118.17400, 3-MPD embodies a blend of unique physical and chemical characteristics that set it apart in the specialty chemical market.

The physical attributes of 3-MPD are notable for their contribution to ease of handling and processing. It boasts a density of 0.974 g/mL at 20 °C and a boiling point of 150 °C at 25mmHg. Its flash point is recorded at 143°C, alongside a refractive index of 1.454. Crucially, 3-MPD is liquid at room temperature, a property that significantly simplifies storage, transportation, and integration into various manufacturing processes, eliminating the need for heating or specialized handling often required for solid diols.

The applications of 3-MPD are extensive and impactful, particularly in the realm of high-performance polymers. It serves as a foundational building block for the synthesis of polyester polyols and polycarbonate polyols, which are indispensable in the production of advanced polyurethane (PU) resins. In these systems, 3-MPD acts as an effective PU resin chain extender, contributing significantly to the final product's mechanical properties and durability. Its incorporation imparts improved adhesion, enhanced softness, and superior resistance to environmental factors, including weather and water.

Beyond polyurethanes, 3-MPD finds wide utility as a key ingredient in plasticizers, where it helps to increase the flexibility and workability of various polymer materials. It is also a vital component in polyester resins for coatings, enabling the formulation of high-quality finishes that offer excellent protective and aesthetic properties. The unique central methyl branch in its structure grants 3-MPD remarkable amorphous properties, leading to polyurethanes with low crystallinity. This structural advantage also makes it ideal for di-substitution, opening avenues for its use as a raw material in the production of diacrylates, essential for certain polymer chemistries. Furthermore, its excellent compatibility with other solvents and inherent transparency make it a valuable solvent for specialized inks.
