Description

4-Chlorotestosterone Acetate is a synthetic, halogenated derivative of testosterone, specifically modified at the 4-position with a chlorine atom and esterified with an acetate group. This structural modification is significant for research into the structure-activity relationships of anabolic-androgenic steroids and their metabolites. It serves as a critical reference standard and intermediate in pharmaceutical research, analytical method development, and biochemical studies. Target users include R&D laboratories, analytical service providers, and manufacturers in the pharmaceutical and life sciences sectors.

Application

• Pharmaceutical Reference Standard: Used for the qualitative and quantitative analysis (HPLC, GC-MS) of steroid compounds in research and quality control laboratories.
• Biochemical Research: Serves as a key intermediate or model compound in studies investigating steroid metabolism, receptor binding, and enzymatic activity.
• Metabolite Studies: Employed in the synthesis and identification of steroid metabolites for toxicological and pharmacological research.
• Analytical Method Development: Crucial for developing and validating chromatographic and spectroscopic methods for steroid detection and quantification.
• Academic & Institutional Research: Used in universities and research institutes for projects related to endocrinology, pharmacology, and medicinal chemistry.
