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.
Doxycycline, the semi-synthetic analog of tetracycline, is a broad-spectrum antibiotic employed in medicine and veterinary applications, is known for its action against a huge range of gram positive and gram negative bacteria. It is prescribed against infections spread by rickettsiae, mycoplasmas and chlamydiae.

Application

Doxycycline hyclate may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations and biological samples by various chromatography and spectrophotometric 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

Mode of Action: Doxycycline hyclate inhibits the inflammatory response to the Lyme Disease Spirochete Borrelia burgdorferi.

Activity Spectrum: Effective against a broad spectrum inhibitor of matrix metalloproteinases in vivo.

Analysis Note

These secondary standards offer multi-traceability to the USP, EP (PhEur) 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.
Values of analytes vary lot to lot.
