Impurities in pharmaceutical products are the unwanted chemicals that remain with the active pharmaceutical ingredients (APIs), or develop during formulation, or upon aging of both API and to medicines. The presence of these impurities even in trace amounts may influence the efficacy and safety of the pharmaceutical products. Identification and quantification of impurities (Impurity Profile) is now becoming important critical product quality parameter and getting critical review from regulatory authorities. Because of this, limit and threshold values for impurities are specified by pharmacopoeias and ICH guidelines. Analysis of impurities according to this set of specifications is mandatory for the pharmaceutical product release for the human consumption. Impurity Profile study is also very important for market approval for finished dosage forms from regulatory authorities.
The identification and quantification of impurity in the pharmaceutical product is carried by using Certified Impurity Standards of known purity. It is recommended to use Impurity Standard having purity at least 90.0 per cent when used for peak identification in the chromatogram or use in the system suitability test for resolution and minimum 95.0 per cent when used to estimate the content of a specified impurity.
VYSHNO BIO SCIENCES offers a wide range of high purity Impurity Standards for the pharmaceutical industries on the milligram to kilogram scale at competitive price. VYSHNO BIO SCIENCES has a technical capability to Synthesize, isolate and purify the Impurity Standards to their purest form. VYSHNO BIO SCIENCES can offer the Impurity Standards from mg to gm scale.
