Descrição geral

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.[1][2]
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.

Aplicação

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.[3][4]

Nota de análise

These secondary standards offer multi-traceability to the USP, EP (PhEur) 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.
