N,N,N',N'-Tetramethyl-1,6-hexanediamine, known by its CAS number 111-18-2 and often abbreviated as TMHDA, is a chemical compound with a unique set of properties that lend it to a variety of industrial applications. As a leading manufacturer and supplier in China, NINGBO INNO PHARMCHEM CO.,LTD. provides this versatile chemical intermediate to industries ranging from polyurethane manufacturing to fine chemical synthesis. Understanding its characteristics is key for formulators and chemists looking to leverage its potential.
Physically, TMHDA is a clear, colorless to yellow liquid. Its molecular formula, C10H24N2, and molecular weight of 172.31 indicate a diamine with significant alkyl substitution. Key physical properties include a boiling point around 209-210 °C and a flash point of approximately 73°C (TCC). Its miscibility with water and other common solvents enhances its usability in various formulations and reaction media. These properties make it an excellent choice for applications requiring a liquid amine.
The primary application for TMHDA is as a polyurethane catalyst. It is widely recognized for its balanced catalytic activity, effectively promoting both the gelation (reaction between isocyanate and polyol) and blowing (reaction between isocyanate and water) reactions in polyurethane systems. This makes it instrumental in the production of flexible foam (slab and molded), semi-rigid foam, and rigid foam, where precise control over reaction kinetics is necessary to achieve desired foam structures and properties. When you buy TMHDA for these applications, you are investing in process efficiency.
In the realm of fine chemistry, N,N,N',N'-Tetramethyl-1,6-hexanediamine serves as a valuable chemical intermediate and building block. Its tertiary amine functionalities allow it to act as a nucleophile or a base in various organic transformations. Furthermore, it functions as an effective acid scavenger, neutralizing acidic species that can interfere with reactions or degrade products. This makes it useful in processes requiring a non-nucleophilic base or where managing acidity is critical. For R&D scientists looking for reliable chemical building blocks, purchasing CAS 111-18-2 from a trusted source is essential.
NINGBO INNO PHARMCHEM CO.,LTD. is committed to delivering high-quality N,N,N',N'-Tetramethyl-1,6-hexanediamine. We pride ourselves on being a reliable supplier, offering competitive prices and excellent customer support. Partner with us to source your TMHDA needs and experience the advantages of working with an experienced chemical manufacturer in China.
