Vitamin standards are used for assay and purity testing of nutritional, pharmaceutical and food-fortification products, where the labelled content has to be supported by an analytical value. Several of these compounds are sensitive to light, heat and oxygen, which is why the assigned value and the storage condition belong together in the laboratory's records. Every lot is certified individually, so the figure used in a calculation can be traced to the material actually weighed.
Folic Acid Sulfate EP Impurity G (CAS 2734707-85-6), molecular formula C19H19N7O6 H2O4S and molecular weight 441.40 98.08. The typical purity published for this item is 92.4171% by HPLC. The typical assay is 89.4%. It is also recorded as Folic Acid EP Impurity G; Folic Acid Hydrate Impurity G [EP Impurity]; L-Glutamic acid, N-[4-[(2-amino-3,4-dihydro-7-methyl-4-oxo-6-pteridinyl)amino]benzoyl]. It is classified under HS code 2936.29.00.00 for export from China; the import classification in your own country may differ. Selected pack sizes are held in stock.

This is the product specification. Typical purity and assay values are those measured on a released lot and stated on that lot’s certificate of analysis; the certificate for the lot shipped with your order travels with the goods. A specification sheet and a certificate of analysis are different documents and are not interchangeable. The HS code shown is the Chinese export classification; the import classification in your own country may differ and should be confirmed with your customs broker. The certificate for the current lot opens from the link above.
