Description

2-Methylbutane-1,4-Diol is a versatile branched-chain diol with significant industrial utility. Its bifunctional nature, featuring both primary and secondary hydroxyl groups, makes it a valuable intermediate for polymerization and specialty synthesis. This compound is particularly sought after by manufacturers in the polymer, pharmaceutical, and fine chemical sectors for producing polyesters, plasticizers, and active pharmaceutical ingredients (APIs).

Application

• Polymer & Resin Intermediate: A key monomer for synthesizing specialty polyesters and alkyd resins, contributing to flexibility and specific performance characteristics.
• Pharmaceutical Synthesis: Serves as a crucial building block (chiral synthon) in the production of various active pharmaceutical ingredients (APIs) and fine chemicals.
• Plasticizer Production: Used in the manufacture of ester-based plasticizers, which are employed to improve the flexibility and workability of polymers like PVC.
• Crosslinking Agent: Functions as a crosslinker in polyurethane and other thermosetting polymer systems, enhancing network density and material properties.
• Solvent & Carrier Fluid: Acts as a high-boiling point solvent or carrier in specialty coatings, inks, and agricultural formulations.
• Lubricant & Hydraulic Fluid Additive: Utilized as a base or additive in synthetic lubricants and functional fluids due to its thermal stability and viscosity properties.

Quality Control

Our 2-Methylbutane-1,4-Diol is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including assay, identity confirmation, and impurity profiling, to ensure it meets the high standards required for industrial and synthetic applications. Certificates of Analysis (COA) documenting purity, physical properties, and safety data are available upon request to support your quality assurance and regulatory compliance needs.

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 to prevent absorption of atmospheric moisture, which can affect product quality.
