说明

General description

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.

Application

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.

Biochem/physiol Actions

L甲状腺素 (T₄) 和三碘代-L-甲状腺原氨酸 (T₃) 为含碘激素，由甲状腺卵泡细胞中的甲状腺球蛋白制备。这些激素对代谢率的刺激以及对生长发展的调节似乎归因于它们对 DNA 转录的作用，进而影响蛋白质的合成。

Analysis Note

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