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. Cholesterol is a waxy material that belongs to the class of sterol-lipids found naturally in foods from animal sources, such as egg yolks, meat, and cheese. It serves as a precursor for the biosynthesis of steroid hormones, bile acid and vitamin D.
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.
Cholesterol may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations and food products by gas chromatography, or by high performance liquid chromatography.
Major component of all biological membranes; ~25% of total brain lipid is cholesterol.
These secondary standards offer multi-traceability to the USP, EP and BP primary standards, where they are available.
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.
