Description
Gibberellic acid (GA) is a tetracyclic di-terpenoid compound and a major hormone synthesized in plants and fungi. It possesses various physiological effects, such as stimulating seed germination, inducing mitotic division of leaves, triggering transitions from meristem to shoot growth, vegetative to flowering, and determining sex expression and grain development through crosstalk with environmental signals like light, temperature, and water.
Uses
Used in Agriculture:
Gibberellic acid is used as a plant growth hormone for promoting the growth and elongation of cells. It is particularly effective in triggering germination in dormant seeds in laboratory and greenhouse settings, stimulating rapid stem and root growth, and inducing mitotic division in the leaves of some plants.
Used in Grape Growing Industry:
In the grape growing industry, gibberellic acid is used as a hormone to induce the production of larger bundles and bigger grapes, boosting the industry's output and quality.
Used in Solid-state Fermentation (SSF):
Gibberellic acid can be produced industrially through solid-state fermentation, which yields relatively high quantities of the hormone, making it more accessible for various applications.
Air & Water Reactions
Slightly water soluble .
Reactivity Profile
Gibberellic acid is readily degraded by acids. .
Fire Hazard
Flash point data for Gibberellic acid are not available. Gibberellic acid is probably combustible.

Biochem/physiol Actions
Phytohormone that controls important aspects of plant growth: germination, elongation, and flowering. The effects are mediated by inducing degradation of the DELLA repressor protein, and probably other minor signalling pathways.
Safety Profile
Mildly toxic by
ingestion. Questionable carcinogen with
experimental tumorigenic data. hlutation
data reported. When heated to
decomposition it emits acrid smoke and
irritating fumes.
Purification Methods
It crystallises from EtOAc, EtOAc/pet ether, MeOH/pet ether or Me2CO/pet ether. [Cross J Chem Soc 3022 1960, Beilstein 18 III/IV 6533.]

Check Digit Verification of cas no
The CAS Registry Mumber 77-06-5 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 7 and 7 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 77-06:
(4*7)+(3*7)+(2*0)+(1*6)=55
55 % 10 = 5
So 77-06-5 is a valid CAS Registry Number.

PHOTOCYCLISIERUNG EINES GIBBERELLINALDEHYDS ZU EPIMEREN CYCLOBUTANOLEN UND DEREN BASISCHE RUECKSPALTUNG, PARTIALSYNTHESE VON 16,17-DIHYDRO-Δ15-GIBBERELLIN-A3
Lischewski, M.,Adam, G.
, p. 45 - 46 (1980)
UV-irradiation of the aldehyde 1 leads to the 7-epimeric cyclobutanols 2a and 2b which undergo upon treatment with NaOCH3 retroaldol-like cleavage to 1 and 3.Oxidation and deacetylation of 3 affords the 16,17-dihydro-Δ15-gibberellin-A3 (5).
Method of manufacturing a dry water-soluble herbicidal salt composition
-
, (2008/06/13)
A method of manufacturing a solid, water-soluble herbicidal composition comprising a water-soluble salt of a herbicidal compound is disclosed. The herbicidal compound is a water-insoluble compound that includes a carboxylic acid functionality, such as a phenoxy-substituted carboxylic acid compound or a substituted benzoic acid compound, and is sufficiently pure to form a dry, solid herbicidal salt composition after interaction with a suitable neutralizing base, such as ammonia, an alkylamine, a dialkylamine, a trialkylamine, a hydroxyalkylamine, a dihydroxyalkylamine, an alkaline salt of an alkali metal or a combination thereof. The dry herbicidal salt composition includes at least about 90% by weight of the water-soluble herbicidal salt, and dissolves rapidly and essentially completely in water to form an aqueous herbicidal solution including up to about 75% by weight of the water-soluble herbicidal salt.
