General description

Hydroxychloroquine Sulfate (Hydroxychloroquine Sulphate) is a salt of hydroxychloroquine (HCQ, Plaquenil), a 4-aminoquinoline based antiviral drug.
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.

Application

Hydroxychloroquine Sulfate can be used as a pharmaceutical secondary standard for the determination of the analyte in pharmaceutical formulations, and biological samples by various analytical techniques.
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.

Biochem/physiol Actions

Hydroxychloroquine sulfate is an anti-inflammatory (via TNF), disease-modifying antirheumatic drug (DMARD), and a heme polymerase inhibitor. It is used in treating malaria.

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.

Hydroxychloroquine, used to treat malaria and some autoimmune disorders, potently inhibits viral infection of SARS coronavirus (SARS-CoV-1) and SARS-CoV-2 in cell-culture studies. However, human clinical trials of hydroxychloroquine failed to establish its usefulness as treatment for COVID-19. This compound is
