Quality Certificate of Analysis

CoA of a reference standard should have data that confirms that the identity (this is an absolute requirement) and its potency (the accuracy requirement for which varies based on application of the reference standard). Additional analysis are required to probe for trace toxic and biologics if a compound will be used for human or animal consumption. Chemtos only synthesizes and sells Analytical reference standards, which cannot be used for consumption/ingestion in humans.

A presentation that discusses various aspects of CoA can be found in the link below:

Are you using poorly characterized (and potentially unacceptable) reference standards? Evaluate whether a CoA with just TLC or limited characterization is adequate for your application.

With our comprehensive certification, you will never need to doubt the authenticity or purity of our reference standards. Every compound provided by Chemtos comes fully certified with Diode Array HPLC purity analysis, proton NMR analysis, LC/MS and all of the supporting data. All analytical work is done under GLP conditions. See a sample CoA.
