Basic Information
Product Name: Gibberellic acid
CAS Number: 77-06-5
Alias: Gibberellin A3, GA3
Molecular Formula: C19H22O6
Molecular Weight: 346.38 g/mol
IUPAC Name: (1S,2R,4aS,4bR,7S,9aR,9bR,10S)-2,7-Dihydroxy-1-methyl-8-methylene-1,2,4a,4b,7,8,9a,9b,10,10a-decahydro-4a,7-methano-10aH-benzo[a]fluorene-10-carboxylic acid
Structural Information
- Structure Type: Natural diterpenoid plant growth regulator
- Structural Features: Contains fused polycyclic skeleton, carboxyl group, hydroxyl groups and exocyclic double bond. The unique molecular structure endows it with strong biological activity to regulate plant growth and development.
Physical & Chemical Properties
- Appearance: White to off-white crystalline powder
- Odor: Odorless
- Melting Point: 233–235 °C (decomposition)
- Specific Rotation: +80° ~ +92° (c=2, ethanol)
- Solubility: Slightly soluble in water; soluble in ethanol, methanol, acetone and aqueous alkaline solution; insoluble in petroleum ether, benzene and chloroform
- Stability: Relatively stable under dry and cool conditions. Gradually decomposes under strong light, high temperature and strong alkaline environment. Avoid contact with oxidants.
Synthesis & Applications
Synthesis Method
Mainly produced by microbial fermentation using Gibberella fujikuroi. After fermentation, the target component is extracted, separated, recrystallized and refined to obtain high-purity finished product. Partial products can be prepared via chemical semi-synthesis.
Main Applications
- Agriculture & Horticulture: Widely used plant growth regulator. Promotes stem elongation, seed germination, flower formation and fruit development; breaks plant dormancy, increases fruit setting rate and improves crop yield.
- Fruit Industry: Induces seedless fruit formation for grapes, citrus and other fruits; accelerates fruit growth and ripening.
- Biological Research: Standard reagent for plant physiology and botany research.
- Gardening: Regulates flowering period of ornamental flowers and improves plant ornamental value.
Safety & Storage Instructions
- Hazard Classification: Low toxicity, mild irritant to skin and respiratory tract
- Personal Protection: Wear dust mask and chemical resistant gloves during operation. Avoid long-term inhalation of dust and direct contact with eyes.
- Storage Condition: Keep containers tightly sealed. Store in cool, dry and dark well-ventilated area. Keep away from heat sources, strong alkali and oxidizing substances.
- Transportation: Belongs to general agricultural chemicals. Prevent package damage, moisture and direct sunlight during transit.
Quality & Spectral Data
- Purity (HPLC): ≥90.0% / ≥99.0%
- Loss on Drying: ≤0.5%
- Residue on Ignition: ≤0.1%
- Heavy Metals: ≤10 ppm
- IR Spectrum: Characteristic absorption peaks are consistent with standard reference spectrum
