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.


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.
Progesterone may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceuticals and environmental samples by liquid chromatography (LC) and gas chromatography/mass spectrometry (GC/MS), liquid chromatography/mass spectrometry (LC/MS) and liquid chromatography/tandem mass spectrometry (LC/MS/MS), respectively.

Biochem/physiol Actions

Induces maturation and secretory activity of the uterine endothelium; suppresses ovulation. Progesterone is implicated in the etiology of breast cancer.

Other Notes

Steroid hormone produced by the corpus luteum.
Values of analytes vary lot to lot.
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.

Analysis Note

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