Descripción

Descripción general

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.

Aplicación

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.

Acciones bioquímicas o fisiológicas

La L-tiroxina (T₄) y la triyodo-L-tironina (T₃) son hormonas que contienen yodo producidas a partir de la tiroglobulina en las células foliculares tiroideas. La estimulación de la tasa metabólica y la regulación del crecimiento y el desarrollo por esas hormonas parece deberse a sus efectos sobre la transcripción del ADN y, por tanto, la síntesis de proteínas.

Nota de análisis

These secondary standards offer multi-traceability to the USP, EP and BP primary standards, where they are available.

Otras 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.
