Description

Butylidynetrimethanol is a versatile triol compound, also known as 2-(Hydroxymethyl)-2-methyl-1,3-propanediol. This multifunctional building block is valued for its ability to introduce hydroxyl functionality and a compact, branched structure into polymer systems. It is primarily sought by formulators and researchers in the polymer and specialty chemical industries. Its unique structure makes it suitable for creating modified resins, cross-linking agents, and performance additives.

Application

• Polymer Synthesis: Serves as a trifunctional monomer or cross-linking agent in the production of alkyd resins, polyesters, and polyurethanes, enhancing hardness and chemical resistance.
• Surface Coatings: Used to formulate high-performance industrial and automotive coatings, improving durability, adhesion, and weatherability.
• Adhesives & Sealants: Incorporated to modify the rheology and cure properties of epoxy, polyurethane, and acrylic-based adhesive systems.
• Lubricant & Fuel Additives: Acts as an intermediate in synthesizing esters that function as viscosity modifiers, detergents, or anti-wear agents.
• Pharmaceutical Intermediates: Utilized as a key chiral building block or protic solvent in the synthesis of active pharmaceutical ingredients (APIs) and other fine chemicals.
• Personal Care Products: Functions as a humectant, emollient, or viscosity regulator in cosmetic and skincare formulations.

Quality Control

Our Butylidynetrimethanol is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and physical properties. A comprehensive Certificate of Analysis (COA) documenting these results is provided with each shipment, ensuring traceability and compliance for your quality assurance protocols.

Storage

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