1,3-Dibutyl-2-thiourea (DBTU), a prominent chemical intermediate, possesses a unique set of properties that make it invaluable in industrial applications, particularly in rubber manufacturing. Understanding its chemical characteristics and synthesis is key for optimal utilization. NINGBO INNO PHARMCHEM CO.,LTD., a leading provider of specialty chemicals, offers insights into this versatile compound.

DBTU, with the chemical formula C₉H₂₀N₂S and CAS number 109-46-6, is typically a white crystalline powder. Its physical properties include a melting point range of 63-65°C and a density of approximately 0.9893 g/cm³. It exhibits limited solubility in water but is more soluble in organic solvents like methanol and ethanol. These properties influence its handling, formulation, and application in various chemical processes. The chemical structure, featuring two butyl groups attached to a thiourea core, dictates its reactivity and functional roles.

The synthesis of DBTU can be achieved through several methods. One common route involves the reaction of n-butylamine with carbon disulfide to form a dithiocarbamate salt, which is then cyclized. Alternative methods, such as propiolactone-mediated synthesis or solvent-free mechanochemical routes, have also been developed to improve efficiency and reduce environmental impact. The choice of synthesis method can affect purity, yield, and cost, which are important considerations when looking to purchase DBTU.

For industries relying on DBTU, sourcing from a reputable DBTU supplier like NINGBO INNO PHARMCHEM CO.,LTD. is crucial. They ensure that the synthesized DBTU meets high purity standards, which is vital for its performance as a vulcanization accelerator and antioxidant. Manufacturers seeking the best price for DBTU should consider the overall value proposition, including product quality, consistency, and supplier reliability.

The safe handling and storage of DBTU are also important. It should be kept in a cool, dry, and well-ventilated area, away from direct sunlight and incompatible materials. When properly stored, DBTU maintains its quality for extended periods.
