Description

2-Methylpentane-2,4-Diol is a versatile branched-chain diol with the CAS number 99113-75-4. This compound serves as a valuable intermediate and functional additive, prized for its dual hydroxyl groups which impart reactivity and polarity. It is particularly sought after by manufacturers in the polymer, specialty chemical, and pharmaceutical sectors for applications requiring controlled hydrophilicity and cross-linking capabilities.

Application

• Polymer Synthesis: Acts as a chain extender or cross-linking agent in the production of polyurethanes, polyesters, and alkyd resins.
• Pharmaceutical Intermediates: Used in the synthesis of active pharmaceutical ingredients (APIs) and other fine chemicals.
• Solvent & Coalescing Agent: Functions as a high-boiling-point solvent and coalescent in coatings, inks, and adhesive formulations.
• Chemical Intermediate: Serves as a key building block for further chemical transformations to produce surfactants, plasticizers, and lubricant additives.
• Personal Care Products: Employed as a humectant and viscosity modifier in cosmetic and personal care formulations.
