Description

1,2-Butanediol is a versatile four-carbon diol with significant industrial utility as a solvent, chemical intermediate, and humectant. Its bifunctional nature, featuring both primary and secondary hydroxyl groups, makes it a valuable building block for synthesizing polymers, plasticizers, and specialty chemicals. This compound is essential for manufacturers in the polymer, cosmetic, pharmaceutical, and agrochemical industries seeking a reliable, high-purity glycol for their formulations and processes.

Application

• Polymer & Resin Production: Serves as a monomer and chain extender in the synthesis of unsaturated polyester resins (UPR), polyurethanes (PU), and alkyd resins.
• Chemical Intermediate: A key precursor for manufacturing plasticizers, cross-linking agents, and other derivatives like 1,2-butylene oxide.
• Cosmetics & Personal Care: Functions as an effective humectant and solvent in skin creams, lotions, and other formulations due to its moisture-retention properties.
• Pharmaceuticals: Used as a solvent and excipient in drug delivery systems and topical applications.
• Agrochemicals: Employed as a solvent and carrier in pesticide and herbicide formulations.
• Industrial Solvent: An effective solvent for dyes, inks, resins, and cellulose esters.
• Deicing Fluids: A component in aircraft and runway deicing formulations due to its low freezing point.

Quality Control

Our 1,2-Butanediol is produced under a stringent quality management system to ensure batch-to-batch consistency and high purity. We provide comprehensive quality assurance, with product specifications meeting or exceeding standard industrial and technical grade requirements. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available for every batch upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 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. Keep away from strong oxidizing agents.
