Descrição geral

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.

Aplicação

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.
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.

Ações bioquímicas/fisiológicas

Componente importante de todas as membranas biológicas; cerca de 25% do teor total de lipídios no cérebro é de colesterol.

Nota de análise

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

Outras notas

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.

Heterozygous familial hypercholesterolaemia is characterised by low cellular uptake of LDL cholesterol, increased plasma LDL cholesterol concentrations, and premature cardiovascular disease. Despite intensive statin therapy, with or without ezetimibe, many patients are unable to achieve recommended target levels of LDL
