Description

11-Keto-Pregnanetriol is a significant steroid metabolite and a key intermediate in the synthesis of various pharmaceutical compounds. This high-purity intermediate is critical for ensuring the quality and consistency of downstream active pharmaceutical ingredients (APIs) and reference standards. It is primarily utilized by research institutions, pharmaceutical manufacturers, and fine chemical producers engaged in steroid hormone research, diagnostic assay development, and the production of advanced therapeutic agents.

Application

• Pharmaceutical Intermediate: A crucial building block in the synthesis of corticosteroid APIs and other steroid-based therapeutics.
• Biochemical Research: Used as a reference standard or reagent in metabolic pathway studies and endocrinology research.
• Diagnostic Manufacturing: Serves as a key component in the production of calibration standards and controls for clinical diagnostic kits, particularly those analyzing adrenal function.
• Analytical Chemistry: Employed as a high-purity standard for method development and validation in chromatographic analyses (HPLC, GC).
• Fine Chemical Synthesis: Utilized in custom synthesis and process development for novel steroid derivatives.
