Description

Guayulin D is a specialized natural product compound isolated from the guayule plant (Parthenium argentatum). This high-purity phytochemical is valued for its unique chemical structure and serves as a critical reference standard and research material. It is primarily sought by research institutions and companies in the pharmaceutical, nutraceutical, and botanical extract sectors for applications in analytical chemistry, bioactivity studies, and product development.

Application

• Analytical Reference Standard: Used as a certified reference material (CRM) for the qualitative and quantitative analysis of guayule resin and related products via HPLC, LC-MS, and GC-MS.
• Phytochemical Research: Serves as a key compound in studies investigating the biosynthetic pathways, chemical ecology, and pharmacological potential of guayule-derived constituents.
• Natural Product Isolation & Purification: Acts as a target molecule for the development and optimization of extraction and chromatographic separation protocols from plant biomass.
• Bioactivity Screening: Utilized in in vitro and in vivo assays to evaluate potential anti-inflammatory, antimicrobial, or other therapeutic properties.
• Quality Control for Botanical Extracts: Employed to standardize and authenticate guayule-based extracts, ensuring batch-to-batch consistency and potency for end-product formulations.
• Chemical Synthesis Intermediate: May be used as a starting material or building block for the semi-synthesis of novel derivatives with modified properties.
