Description

Dl-Thyronine CAS NO 1034-10-2 is a synthetic thyroid hormone analog, specifically the racemic mixture of thyronine. This compound is a critical intermediate and reference standard in pharmaceutical research and development, particularly for studying thyroid function and metabolism. It serves as a key building block for endocrinologists, medicinal chemists, and manufacturers developing diagnostic reagents and therapeutic agents targeting thyroid-related disorders.

Application

• Pharmaceutical Intermediate: Serves as a crucial precursor in the synthesis of more complex thyroid hormone analogs and active pharmaceutical ingredients (APIs).
• Biochemical Research: Used as a reference standard and research tool in studies of thyroid hormone action, receptor binding, and metabolic pathways.
• Diagnostic Reagent Manufacturing: Employed in the production of calibration standards and components for in-vitro diagnostic (IVD) kits that measure thyroid function.
• Endocrinology Studies: Essential for in-vitro and in-vivo research models investigating hyperthyroidism, hypothyroidism, and related metabolic diseases.
• Academic & Industrial R&D: Provides a foundational compound for drug discovery programs focused on nuclear hormone receptors.

Quality Control

Our Dl-Thyronine is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets rigorous standards suitable for research and pharmaceutical applications. Certificates of Analysis (COA) with detailed batch-specific results are provided to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its light-sensitive nature and propensity to be easily oxidized, it is recommended to store the product under an inert atmosphere for long-term stability and to minimize degradation.
