Description

Gibberellin A4 Methyl Ester is a potent, synthetic derivative of the gibberellin plant hormone family, specifically Gibberellin A4. This compound is valued for its high biological activity and stability, making it a crucial tool for plant physiology research and agricultural biotechnology. It is primarily sought by researchers and formulators in the agrochemical, horticultural, and plant science industries for applications requiring precise hormonal control.

Application

• Plant Growth Regulation & Research: Used as a key reference standard and active ingredient in studies of gibberellin biosynthesis, signal transduction, and plant developmental processes.
• Seed Germination & Dormancy Breaking: Applied to stimulate uniform seed germination and overcome dormancy in various plant species under controlled conditions.
• Fruit Setting & Development: Employed in experimental protocols to induce parthenocarpy (seedless fruit development) and improve fruit set and size in specific crops.
• Stem Elongation & Bolting Studies: A critical reagent for investigating and promoting stem elongation, particularly in rosette plants, for research purposes.
• Plant Tissue Culture: Incorporated into growth media to enhance cell division and differentiation in in vitro culture systems.
• Agrochemical Formulation R&D: Serves as a high-purity intermediate or active component in the development of novel plant growth regulator (PGR) formulations.

Quality Control

Our Gibberellin A4 Methyl Ester is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets high-purity research-grade standards. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and consistency for your critical research and development work.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C (refrigerated) or as indicated on the label or COA. This product is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to minimize exposure to atmospheric humidity.
