Description

11-Fluoro-19-Nordihydrotestosterone is a synthetic fluorinated steroid derivative, structurally related to dihydrotestosterone (DHT). This compound is of significant interest in pharmaceutical research and development due to its potential as a potent and selective androgen receptor modulator. It serves as a critical intermediate and reference standard for researchers in the life sciences, particularly those focused on endocrinology, metabolic studies, and the development of novel therapeutic agents. The product is supplied with a guaranteed high level of purity and batch-to-batch consistency to support rigorous scientific inquiry.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of advanced steroid-based drug candidates.
• Biochemical Research: Used as a reference standard and tool compound in studies investigating androgen receptor (AR) signaling pathways and function.
• Endocrinology Studies: Applied in preclinical research to explore the effects of modified androgens on metabolism, muscle growth, and related physiological processes.
• Metabolic Research: Utilized in laboratory settings to study the interaction of fluorinated steroids with metabolic enzymes and receptors.
• Analytical Standard: Provides a high-purity benchmark for quality control and method development in analytical chemistry (e.g., HPLC, LC-MS).
• Life Science Reagent: Employed in cell-based assays and in vitro studies to modulate androgen-responsive systems.
