General description

Anthralin (Dithranol) is the synthetic form of chrysarobin. It is widely used as a medication for the human skin affected with psoriasis and in short contact therapy to minimize the staining, irritation, etc.
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

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.
Anthralin (Dithranol) may be used as a pharmaceutical reference standard for the quantification of the analyte in pharmaceutical formulations using high pressure liquid chromatography.

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.
