Description

2-(Hydroxymethyl)Butane-1,3-Diol is a versatile polyfunctional alcohol, also known as trimethylolethane, with significant utility as a building block in advanced organic synthesis. Its value lies in its trifunctional nature, offering three reactive hydroxyl groups that enable the creation of polymers, resins, and specialty esters with tailored properties. This compound is essential for industries focused on producing high-performance coatings, plasticizers, and pharmaceutical intermediates where precise molecular architecture is required.

Application

• Polymer & Resin Synthesis: A key monomer for producing alkyd resins, polyesters, and polyurethanes, imparting hardness and chemical resistance to coatings and adhesives.
• Plasticizer Production: Used to synthesize ester-based plasticizers, which are employed to improve the flexibility and durability of PVC and other polymers.
• Pharmaceutical Intermediates: Serves as a crucial chiral building block and precursor in the synthesis of active pharmaceutical ingredients (APIs) and drug delivery systems.
• Crosslinking Agent: Functions as an effective crosslinker in thermosetting polymers, enhancing thermal stability and mechanical strength in final products.
• Lubricant & Synthetic Oil Additive: Utilized in formulating synthetic lubricants and functional fluids due to its stability and viscosity-modifying properties.
• Personal Care & Cosmetics: Incorporated as a humectant and conditioning agent in skincare and haircare formulations.

Quality Control

Our 2-(Hydroxymethyl)Butane-1,3-Diol is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, moisture content, and impurity profiles are provided with every shipment to guarantee supply reliability and batch-to-batch consistency for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
