Description

25S-Inokosterone is a specific stereoisomer of the ecdysteroid inokosterone, a naturally occurring steroid hormone analog with significant bioactivity. This high-purity compound is valued for its role as a critical reference standard and active ingredient in advanced life science research and development. It is essential for researchers and manufacturers in the pharmaceutical, nutraceutical, and agrochemical sectors who require precise, well-characterized bioactive compounds for product development and quality control.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for the identification, assay, and purity testing of ecdysteroid-based products in QC laboratories.
• Biochemical Research: Serves as a key reagent in studies of insect endocrinology, growth regulation, and the mode of action of steroid hormones.
• Nutraceutical Development: Investigated as a potential active component in performance-enhancing or anabolic dietary supplements due to its ecdysteroid properties.
• Agrochemical Research: Utilized in the development and testing of novel, environmentally friendly insect growth regulators (IGRs) and pesticides.
• Academic Studies: Employed in university and institutional research exploring steroid signaling pathways and comparative endocrinology.
