Description

Azadirachtin B(Sh) CAS NO 106500-25-8 is a highly potent, specific limonoid tetranortriterpenoid compound, representing a key bioactive constituent derived from the neem tree (*Azadirachta indica*). This compound is critically important for its role as a benchmark analytical standard and a precursor for advanced botanical pesticide research and development. It is primarily required by agrochemical R&D laboratories, manufacturers of biopesticides, and academic institutions focused on natural product chemistry and insect growth regulation.

Application

• Analytical Reference Standard: Used for the qualitative and quantitative analysis (HPLC, LC-MS) of neem-based extracts and formulations to ensure potency and consistency.
• Biochemical Research: Serves as a critical tool for studying insect endocrinology, specifically the disruption of ecdysone and juvenile hormone systems.
• Active Ingredient (AI) in Biopesticides: Acts as a core active component in the formulation of eco-friendly, targeted insecticides and antifeedants.
• Product Development & Standardization: Essential for the development, quality control, and standardization of commercial botanical insecticide products.
• Structure-Activity Relationship (SAR) Studies: Used as a molecular scaffold to synthesize novel analogs with enhanced insecticidal properties or improved stability.
• Toxicological and Environmental Fate Studies: Employed as a pure compound to assess non-target organism effects and environmental degradation pathways.

Quality Control

Our Azadirachtin B(Sh) is produced and handled under strict quality protocols to ensure high purity and batch-to-batch consistency, suitable for research and development purposes. Each batch is analyzed using advanced chromatographic techniques, including HPLC and LC-MS, to confirm identity and potency. A comprehensive Certificate of Analysis (COA) detailing purity, related substances, and analytical methods is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below under an inert atmosphere. The product is light-sensitive (store away from light). Allow the sealed vial to equilibrate to room temperature before opening to prevent moisture condensation.
