Description

Lhrh CAS NO 35263-73-1 is a synthetic peptide analog of the natural gonadotropin-releasing hormone (GnRH). This compound is a critical intermediate and active pharmaceutical ingredient (API) used in advanced therapeutic and diagnostic applications. It is essential for researchers and manufacturers in the pharmaceutical and biotechnology sectors developing treatments for hormone-dependent conditions. The high-purity grade ensures reliable performance in sensitive biological assays and formulation processes.

Application

• Pharmaceutical API: Core component in the synthesis of hormone therapy drugs for oncology and endocrinology.
• Research & Development: Used as a reference standard and biochemical tool in preclinical studies of reproductive endocrinology.
• Diagnostic Kits: Key reagent in the development of immunoassays and diagnostic tests for hormonal function.
• Veterinary Medicine: Employed in fertility control and reproductive management solutions for animals.
• Peptide Synthesis: Serves as a fundamental building block for creating more complex peptide conjugates and analogs.
