Cosyntropin(CAS: 16960-16-0)

Cosyntropin is a synthetic hormone with a molecular weight of approximately 342.43 g/mol. It is a white to off-white crystalline powder with a melting point of 180-185°C. Cosyntropin is poorly soluble in water but soluble in organic solvents. It is stable under normal storage conditions but degrades under alkaline or acidic conditions. It is not reactive with common chemicals but should be handled with care to prevent contamination.

Cosyntropin is synthesized through a multi-step chemical process involving amino acid coupling and acylation. The key steps include the coupling of amino acids to form the peptide backbone, followed by side-chain modifications. The synthesis typically involves the use of coupling reagents like HATU or EDC, and the reaction is carried out in organic solvents like DMF. The yield is usually between 60-80%, and the product is purified by HPLC or chromatography.

Cosyntropin is primarily used in the pharmaceutical industry, particularly in the treatment of adrenal insufficiency, as a diagnostic tool for diagnosing primary or secondary adrenal insufficiency, and in the treatment of hypotension. It is also used in research for its anti-inflammatory and immunomodulatory properties. Additionally, it has applications in veterinary medicine for the treatment of hypoadrenocorticism in animals.

When handling Cosyntropin, it is essential to wear personal protective equipment (PPE) such as gloves, goggles, and a lab coat. It should be stored in a cool, dry place away from light and moisture. Fume hoods should be used when mixing or dissolving the compound. In case of a spill, immediately clean up with water and dispose of the waste according to local regulations. Always refer to the Safety Data Sheet (SDS) for detailed safety information and emergency procedures.
