Folic acid Impurity A

Folic acid Impurity A is an organic compound that is commonly used as an impurity reference standard in the pharmaceutical industry. It is a known impurity that is sometimes present in folic acid formulations, and its presence can have an impact on the efficacy and safety of the drug. Chemically, Folic acid Impurity A is a derivative of folic acid that has a molecular formula of C19H17N7O6. It is classified as a pteridine and is a yellowish-brown powder that is soluble in water and organic solvents like ethanol and methanol. In terms of usage, Folic acid Impurity A is primarily used in analytical laboratories to develop and validate analytical methods for the detection and quantification of impurities in folic acid formulations. It is also used as a reference standard for the identification and characterization of impurities in pharmaceutical products. The presence of Folic acid Impurity A in folic acid formulations can impact the efficacy and safety of the drug. It is therefore important to monitor and control the levels of this impurity in pharmaceutical products. The allowable limit for Folic acid Impurity A in folic acid formulations is typically set by regulatory authorities like the United States Pharmacopeia (USP) and the European Pharmacopeia (EP). In summary, Folic acid Impurity A is an important reference standard used in the pharmaceutical industry to ensure the quality and safety of folic acid formulations. Its chemical properties and usage make it a valuable tool for analytical laboratories and regulatory authorities.
