Properties and Physical CharacteristicsN,N-Dimethyl-P-Toluidine presents as a colorless to pale yellow liquid with an aromatic, amine-like odor. It has a boiling point of 211C and is slightly soluble in water, but highly soluble in organic solvents. The chemicals density is 0.94 g/cm and exhibits a refractive index of n20/D 1.543. Sensitivity to air and light requires protective storage conditions to maintain appearance and quality.
Recommended Storage and StabilityThis compound should be stored in tightly closed containers and placed in a cool, well-ventilated environment, away from light and air to prevent degradation. DMPT remains stable for up to 12 months under proper storage, though it may darken if exposed to light or air. Packaging is available in HDPE drums25 kg or 200 kg formatsto ensure safety and minimal exposure during transport and storage.
Applications and Industrial UsageDMPT is predominantly employed as a promoter or catalyst in adhesive formulations and polymer curing processes. It is integral to the production of dental resins and various industrial adhesives, enhancing polymerization efficiency. Its use ensures effective initiation and acceleration of polymerization, making it valuable for manufacturers in chemical industries and the dental sector.
