 At CRS we understand how important it is to provide the best quality to our customers, and that is why we strive to achieve the highest purity for our reference standards.

Our Certificate of Analysis includes HPLC, NMR, Mass, TGA, and IR analysis complete with their raw data and results as well as brief explanation or elucidation. To obtain better results, depending on the chemistry of the compound some tests may be replaced or added for more accurate determinations.
