Descripción

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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Aplicaciones
La 1,1,3,3-tetrametilguanidina se emplea como catalizador de espuma de poliuretano, como acelerador para las síntesis del caucho polisulfurado. También se utiliza como base fuerte en las industrias fotoquímicas (acopladores) y farmacéuticas (esteroides). Es esencial para la preparación de nitrilos de alquilos a partir de haluros de alquilo y 3′-alquiltimidinas a partir de 3′-nitrotimidinas. Sirve como catalizador eficaz y selectivo para la benzoilación de alcoholes. Reemplaza las bases caras 1,8-diazabiciclo[5.4.0]undec-7-eno (DBU) y 1,5-diazabiciclo[4.3.0]non-5-eno (DBN) en la síntesis orgánica.
