6-Amino-1,3-dimethyluracil is a high-performance, eco-friendly chemical additive primarily utilized as a non-toxic heat stabilizer for PVC and a critical intermediate in pharmaceutical synthesis. Designed to replace hazardous heavy-metal stabilizers, this versatile compound ensures superior thermal stability and weather resistance, making it an essential choice for manufacturers committed to sustainable and green chemical production.
By effectively absorbing ultraviolet rays and neutralizing HCl released during processing, it prevents the degradation of PVC resin at high temperatures. Whether used as a plasticizer to improve flexibility or as a synthetic material intermediate for rubber and polymers, our 6-Amino-1,3-dimethyluracil provides a balanced combination of purity, efficiency, and environmental safety, compliant with international standards like REACH and ROHS.

It acts as a PVC heat stabilizer that prevents thermal degradation during processing by neutralizing HCl and absorbing UV rays, thereby improving the aging resistance and stability of the plastic.
Yes, it is designed specifically to replace toxic lead and cadmium salts, offering equivalent thermal stability while being non-toxic and environmentally friendly.
Absolutely. Due to its unique structural characteristics, it serves as a vital intermediate for the synthesis of various drugs with specific biological activities.
Hard PVC (used for doors/windows) uses the stabilizer without plasticizers for high strength, while soft PVC (used for films/leather) combines it with plasticizers for flexibility.
The product is backed by EU REACH, TURKEY KKDIK, EU ROHS, and ISO certifications (9001, 14001, and 45001).
Unlike ordinary stabilizers, 6-Amino-1,3-dimethyluracil can absorb ultraviolet rays, which significantly reduces degradation caused by sun exposure and extends the product's lifespan.
