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. L-Lysine is an essential proteinogenic α-amino acid, containing basic side chain and is hydrophilic in nature. L-Lysine is actively used in the form of its acetate salt. It serves as a precursor for secondary metabolites, such as β-lactam antibiotics. It also serves as a precursor for the biosynthesis of α-aminoadipic acid.
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.
These secondary standards offer multi-traceability to the USP, EP (PhEur) and BP primary standards, where they are available.
Values of analytes vary lot to lot.
