Descrição geral

Levothyroxine is a thyroid hormone that is responsible for the physiological actions such as growth, cardiac functionality, and regulation of carbohydrates, lipid, and protein metabolisms.
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.

Aplicação

Levothyroxine may be used as a pharmaceutical reference standard for the quantification of the analyte in pharmaceutical formulations and bulk dosage forms and oral liquid formulations by chromatography.
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.

Ações bioquímicas/fisiológicas

L-Thyroxine (T4) and triiodo-L-thyronine (T3) are iodine-containing hormones produced from thyroglobulin in the thyroid follicular cells. The stimulation of metabolic rate and regulation of growth and development by these hormones appear to be due to their effects on DNA transcription and, thus, protein synthesis.

Nota de análise

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