General description
L-Threonine is an essential amino acid. It is involved in the synthesis of mucin, a protein supporting intestinal function and integrity. L-threonine has a role in the immune system, in O-linked glycosylation, protein phosphorylation and glycine synthesis.
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.
Application
L-Threonine may be used as a pharmaceutical reference standard for the quantification of the analyte in pharmaceutical formulations using high-performance liquid chromatography technique.
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.
Analysis Note
These secondary standards offer multi-traceability to the US and EP primary standards, where they are available.
These secondary standards offer multi-traceability to the USP, EP (PhEur) and BP primary standards, where they are available.
