General description
Tryptophan is an essential amino acid and a precursor for the synthesis of serotonin (5-HT), a neuromodulator responsible for modulating sleep and appetite regulation.
Certified pharmaceutical secondary standards for application in quality control provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to in-house working standards.
Certified pharmaceutical secondary standards for application in quality control provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to in-house working standards.
Application
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.
Tryptophan may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations by spectrophotometric techniques.
Analysis Note
These secondary standards offer multi-traceability to the USP and EP (PhEur) primary standards, where they are available.
