1739-83-9 Usage
General Description
1,2,4,5-Tetramethylimidazole is a chemical compound with the molecular formula C7H12N2. It is a colorless to yellowish liquid with a strong amine-like odor. 1,2,4,5-TETRAMETHYLIMIDAZOLE is primarily used as a catalyst in the production of polyurethane and as a curing agent for epoxy resins. It is also utilized in the synthesis of pharmaceuticals and agrochemicals. Additionally, 1,2,4,5-Tetramethylimidazole has found applications in the electronics industry, where it is used as an additive in the fabrication of photoresist polymers. However, it is important to handle this chemical with caution as it is flammable and can cause skin and eye irritation upon contact.
Check Digit Verification of cas no
The CAS Registry Mumber 1739-83-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,3 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1739-83:
(6*1)+(5*7)+(4*3)+(3*9)+(2*8)+(1*3)=99
99 % 10 = 9
So 1739-83-9 is a valid CAS Registry Number.

Evjen, Sigvart,Fiksdahl, Anne
supporting information, p. 1392 - 1399 (2017/07/25)
We have developed improved general simple methods for large-scale preparation of polyalkylated imidazoles by improved multicomponent synthesis from commercially available starting materials. A large range of NH- and N-alkyl-polyalkylimidazoles (40 in total, including novel compounds) has been synthesized.
