999-22-4 Usage
General Description
N,N''-ethylenebis[N-methylpropane-1,3-diamine] is a chemical compound used as a cross-linking agent in the production of polyurethane foams, elastomers, and coatings. It is a diamine compound with two N-methylpropane-1,3-diamine groups connected by an ethylene bridge. N,N''-ethylenebis[N-methylpropane-1,3-diamine] is known for its ability to improve the physical properties and performance of polyurethane materials by forming strong cross-links, which enhance the material's strength, durability, and resistance to abrasion and chemicals. Additionally, N,N''-ethylenebis[N-methylpropane-1,3-diamine] has been used as a curing agent in epoxy resins and as a component in some pharmaceuticals and agrochemicals. It should be handled and used with proper safety precautions due to its potential irritant and sensitizing properties. Overall, this chemical plays a key role in the production of various polyurethane and epoxy-based materials with enhanced performance characteristics.
Check Digit Verification of cas no
The CAS Registry Mumber 999-22-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,9 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 999-22:
(5*9)+(4*9)+(3*9)+(2*2)+(1*2)=114
114 % 10 = 4
So 999-22-4 is a valid CAS Registry Number.
