Description

11-Ketoandrosterone β-D-Glucuronide is a specific conjugated metabolite of androsterone, formed via glucuronidation. This compound is of significant value as a high-purity reference standard and a critical intermediate in biochemical research and diagnostic development. It is primarily needed by pharmaceutical R&D laboratories, clinical diagnostic manufacturers, and academic institutions focused on steroid metabolism, endocrinology, and analytical method validation.

Application

• Reference Standard for Analytical Chemistry: Used as a certified reference material (CRM) for the quantification of steroid metabolites in biological matrices via LC-MS/MS or GC-MS.
• Diagnostic Kit Development: Serves as a key calibrator or component in the production of immunoassays and test kits for hormonal and metabolic disorder profiling.
• Biomedical Research: Employed in studies investigating androgen metabolism pathways, enzyme activity (e.g., UDP-glucuronosyltransferases), and metabolic disorders.
• Pharmaceutical Impurity Profiling: Used to identify and quantify related substances or degradation products in steroid-based pharmaceutical products.
• Forensic Toxicology: Acts as a marker or standard in the analysis of anabolic steroid abuse and endogenous steroid profiles.
• Metabolomics Studies: Incorporated into targeted metabolomics panels for the comprehensive analysis of steroid hormone pathways.

Quality Control

Every batch of 11-Ketoandrosterone β-D-Glucuronide is manufactured and controlled under a strict quality management system. Our products undergo rigorous identity, purity, and assay testing using advanced analytical techniques such as HPLC, NMR, and MS to ensure compliance with high-purity reference standard requirements. A comprehensive Certificate of Analysis (COA) detailing batch-specific results is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C. This product is hygroscopic (moisture-sensitive) and should be handled under anhydrous conditions to maintain stability and purity. Allow the sealed container to equilibrate to room temperature before opening to prevent moisture condensation.
