Description

Lecirelin is a synthetic nonapeptide analog of gonadotropin-releasing hormone (GnRH). This compound is a potent agonist of the GnRH receptor, playing a critical role in regulating the hypothalamic-pituitary-gonadal axis. It is primarily utilized in pharmaceutical research and development for applications in endocrinology, oncology, and reproductive medicine. The product is supplied as Lecirelin CAS NO 61012-19-9, ensuring high purity and consistency for demanding industrial and research applications.

Application

• Pharmaceutical Active Ingredient (API): Used in the formulation of therapeutic agents for hormone-dependent conditions.
• Endocrinology Research: A key tool for studying the GnRH pathway, pituitary function, and hormone release mechanisms.
• Oncology Research: Investigated for its potential in the treatment of hormone-sensitive cancers, such as prostate and breast cancer.
• Veterinary Medicine: Employed in fertility control and the treatment of reproductive disorders in animals.
• Diagnostic Agent Development: Used in the development of diagnostic tests for assessing pituitary gland function.
• Biochemical Standard: Serves as a high-purity reference standard in analytical laboratories for quality control and method validation.
