Description
In organic synthesis, 1,1,3,3-tetramethylguanidine is used as a strong, non-
nucleophilic base. 1,1,3,3-tetramethylguanidine is an efficient and selective
catalyst for alcohol benzoylation.
Physical and chemical properties tetramethylguanidine is a colorless oily
liquid, boiling point 160-162℃, density 0.918, refractive index 1.4692, is a
strong organic base, soluble in toluene, cyclohexanone, ethanol, etc., also
Chemicalbook soluble in water, easily hydrolyzed to tetramethyl urea in
alkaline aqueous solution, corrosive, generally packed in galvanized iron
drums.
Applications
NT CAT TMG can also be used as a catalyst for polyurethane foam and for even
dyeing of nylon, wool and other proteins to improve the durability of wool,
etc. It is mainly used in the synthesis of cefradine and other drugs.

Storage Information
NEWTOP Chemical recommends that our catalysts be stored in a dry and cool area
under appropriate ventilation conditions. Each container should be closed
tightly to avoid contamination with moisture or other negative influences that
could change the products performance in the end use. The optimum storage
temperature is between 10 °C and 30° C. Lower and higher storage temperatures
are not preferable and should be avoided.
