Frequently Asked Questions
In the pharmaceutical industry, DMAU is primarily used as a key intermediate for the synthesis of Theophylline and other related xanthine derivatives used in respiratory treatments.
Many countries have banned lead salts due to toxicity. DMAU is a high-efficiency, safe alternative based on a nucleotide structure that is non-hazardous to humans while providing equal or better stability.
DMAU absorbs HCl produced during PVC processing. When used with ZnSt2, it reacts with ZnCl2 to create a metal complex, neutralizing the activity of ZnCl2 and preventing the PVC from darkening.
Yes, adding 3-4% DMAU combined with 8-10% hydrotalcite or aluminosilicate into a Calcium/Zinc stabilizer can improve initial colorlessness while remaining more economical.
While it depends on the specific product, our usual MOQ is as low as 1kg, making it accessible for both R&D testing and large-scale industrial production.
We employ a dedicated Quality Control Department that tests every batch. We provide a Certificate of Analysis (COA) for each order and welcome third-party inspections to verify our specs.
