General description

Certified pharmaceutical secondary standards for application in quality control provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to pharmacopeia primary standards.
Retinyl palmitate belongs to a category of compounds called retinoids, which are chemically similar to vitamin A. It exhibits a beneficial effect on vision, skin and immune function, inhibits cell proliferation and prevents cancer. It is an important dietary as well as a therapeutic compound.


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.
Retinyl palmitate may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations by chromatographic and spectrophotometric techniques.

There are inverse relationships between HDL cholesterol and plasma triacylglycerol concentrations in normal and in hypertriglyceridemic individuals. To investigate the interactions between triacylglycerol-rich lipid particles and HDL, a lipid emulsion model of the triacylglycerol-rich lipoproteins was prepared. When emulsion particles...
