General description

Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.
Quercetin is a flavanol with strong antioxidant property. Due to the ability to scavenge free radicals and bind transition metal ions, quercetin is commonly used as a nutritional supplement and physiochemical remedy for a large number of diseases.

Application

These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.
Quercetin may be used as a pharmaceutical reference standard for the analysis of the analyte in biological samples and pharmaceutical formulations by high performance liquid chromatography (HPLC) and spectrophotometric methods.

Analysis Note

These secondary standards offer multi-traceability to the USP, EP and BP primary standards, where they are available.

Other Notes

This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.
