CAS 80-70-6: 1,1,3,3-Tetramethylguanidine

1,1,3,3-Tetramethylguanidine is employed as a polyurethane foam catalyst, as an accelerator for the syntheses of polysulfured rubber. It is also used as a strong base in the photochemical (couplers) and in the pharmaceutical (steroids) industries. It is essential for the preparation of alkyl nitriles from alkyl halides and 3'-alkylthymidines from 3'-nitrothymidines. It serves as an efficient and selective catalyst for the benzoylation of alcohols. It replaces the expensive bases 1,8-Diazabicyclo[5.4.0]undec-7-ene (DBU) and 1,5-Diazabicyclo[4.3.0]non-5-ene (DBN) in organic synthesis.

1,1,3,3-Tetramethyl guanidine is a reactive nitrogen compound that has the ability to react with metal hydroxides. It is used in chemical synthesis and as an additive in paints. 1,1,3,3-Tetramethyl guanidine forms adducts with metal hydroxides at elevated temperatures. The addition of water to this reaction can produce hydrogen gas and ammonia gas. 1,1,3,3-Tetramethyl guanidine is also known for its high resistance to heat and chemicals. It is stable under acidic conditions and can be used as a stabilizer for organic esters. The thermal expansion coefficient of 1,1,3,3-tetramethyl guanidine can be calculated by x-ray crystallography data. The molecular structure of 1,1,3,3-tetramethyl guanidine was determined as a result of x-ray diffraction studies on dna dup
