Description

(5α,8β,9α,10β,13S)-13-Methyl-17-Norkaur-15-En-19-Oic Acid is a high-purity diterpenoid carboxylic acid derivative, valued for its complex, rigid kaurane-type skeleton. This compound serves as a critical advanced pharmaceutical intermediate and a versatile scaffold in organic synthesis for the development of novel bioactive molecules. It is primarily sought by research institutions and manufacturers in the pharmaceutical, agrochemical, and fine chemical sectors for drug discovery and process chemistry applications.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel drug candidates, particularly those targeting neurological or metabolic pathways.
• Medicinal Chemistry Research: Used as a core scaffold for structure-activity relationship (SAR) studies and library synthesis due to its complex, polycyclic structure.
• Natural Product Synthesis: Serves as a starting material or intermediate in the semi-synthesis or total synthesis of complex natural products with kaurane diterpenoid backbones.
• Agrochemical Development: Investigated as a precursor for developing new plant growth regulators or pesticides with novel modes of action.
• Biochemical Tool Compound: Utilized in biochemical assays to study enzyme interactions or biological pathways influenced by diterpenoid structures.
• Fine Chemical Synthesis: Employed in the preparation of specialty chemicals, flavors, or fragrances requiring a specific chiral and structural framework.
