Our product is Factory Supply Terephthalaldehyde with CAS number 623 - 27 - 8. Terephthalaldehyde is an important organic compound. It has a molecular formula of C₈H₆O₂ and a molecular weight of approximately 134.13 g/mol.
It appears as a white to light - yellow crystalline powder. This compound is sparingly soluble in water but soluble in many organic solvents such as ethanol, acetone, and chloroform. It has a melting point in the range of 114 - 116 °C.
Terephthalaldehyde has a wide range of applications in various industries. In the field of organic synthesis, it serves as a key intermediate. It can be used to synthesize a variety of heterocyclic compounds, which are often used in the production of pharmaceuticals, agrochemicals, and advanced materials.
In the polymer industry, it can be used as a cross - linking agent. By reacting with polymers, it can improve the mechanical properties, chemical resistance, and heat resistance of polymers. Additionally, it is used in the production of fluorescent materials. The unique structure of terephthalaldehyde allows it to be incorporated into fluorescent dyes, which have applications in biological imaging, sensors, and optical displays.
When using Terephthalaldehyde, it is essential to follow proper safety procedures. Always wear appropriate personal protective equipment, including gloves, goggles, and a lab coat.
For laboratory use, accurately weigh the required amount of terephthalaldehyde using a balance. Then, dissolve it in a suitable organic solvent under stirring. The dissolution process should be carried out in a well - ventilated area, preferably in a fume hood. When using it as a cross - linking agent in polymer synthesis, carefully control the reaction conditions, such as temperature, reaction time, and the molar ratio of terephthalaldehyde to the polymer.
Case 1: Pharmaceutical Synthesis
In a pharmaceutical research project, terephthalaldehyde was used to synthesize a new anti - cancer drug. The researchers first dissolved terephthalaldehyde in ethanol and then reacted it with a specific amino - containing compound. The reaction was carried out at a temperature of 60 °C for 6 hours. After purification, the resulting compound showed significant anti - cancer activity in in - vitro tests. The yield of the final product was approximately 70%, indicating that terephthalaldehyde can be effectively used in pharmaceutical synthesis.
Case 2: Polymer Cross - linking
A polymer manufacturing company used terephthalaldehyde to cross - link a polyamide resin. They added terephthalaldehyde to the polyamide solution at a molar ratio of 1:5. The mixture was heated to 120 °C for 3 hours under an inert atmosphere. The cross - linked polymer showed a 30% increase in tensile strength and a 20% improvement in chemical resistance compared to the non - cross - linked polymer. This case demonstrates the potential of terephthalaldehyde in enhancing the performance of polymers.
