Other Reasons To Import Quetiapine Fumarate From Us
As mentioned above, our quetiapine is manufactured in GMP factories at competitive prices.
If that has not made up your mind about working with us, our high-quality standards below will help assure you of this.
1) Control of impurities:
As we all know, the higher the purity, the better.
But not all of us know that the content of impurities is even more important than the testing value of purity.
USP has requirements of less than 0.15% for known impurities, and below 0.1% for unknown single impurities, this is tough right?
If you check our testing results on those impurities by the Certificate of analysis below, you will find our impurity control is extremely high.
Known impurities are not more than 0.01%, and unknown impurities are 0.008% with total impurities of 0.05%.
Now you see what our so-called high quality means.
2) Low content of Residual solvents:
All four solvents used in the synthesis and purification of quetiapine are methanol, ethanol, toluene, and N, N-Diethylaniline.
Testing results are showing that there are no methanol and N, N-Diethylaniline left in our quetiapine, and the content of ethanol and Toluene is 0.07% and 0.006%.
Low contents of residual solvents are the reflections of the optimization of our synthesis process, which is also what we are proud of.
3) Testing results of Residue on Ignition/Loss on Drying
The value of Loss on Drying is reflecting the content of volatile matter such as water and solvents.
Our testing results of Loss on Drying is only 0.09%, way below the USP requirements of 0.5%.
As for the Residue of Ignition, it is the indicator of the content of inorganic matter with the API, the smaller, the better.
If the value is small, it means there is low content of inorganic matter.
Our testing results for Residue of Ignition is 0.03%, also way lower than The USP requirements of NMT0.1%.
From all those 3 points above you can see that the quality of our quetiapine fumarate is extremely high.
If you are still not sure, request a sample to test for yourself on the quality.
