Description

Gibberellin A(19) is a specific member of the gibberellin family of plant hormones, identified by CAS No. 6980-44-5. This compound is valued for its role in advanced plant physiology research and as a critical reference standard for analytical and bioassay applications. It is essential for researchers and manufacturers in the agricultural biotechnology, plant science, and fine chemical synthesis sectors who require high-purity, well-characterized phytohormones.

Application

• Plant Physiology & Biochemistry Research: Used as a pure reference compound to study gibberellin biosynthesis pathways, metabolism, and signal transduction mechanisms.
• Analytical Reference Standard: Serves as a high-purity calibrant for quantitative analysis (e.g., HPLC, LC-MS) of gibberellin content in plant tissues, commercial products, and complex matrices.
• Bioassay Standard: Provides a defined active ingredient for developing and validating biological assays that measure gibberellin-like activity.
• Fine Chemical Synthesis: Acts as a key intermediate or starting material for the synthetic preparation of novel gibberellin analogs and derivatives with tailored biological properties.
• Agricultural Biotechnology: Employed in controlled experiments to investigate and manipulate plant growth traits such as stem elongation, seed germination, and flowering.
