Gibberellic acid( GA3) 77-06-5
Category : Agrochemicals/Plant growth regulator
CAS NO : 77-06-5 EC NO : 201-001-0 MF : C19H22O6 MW : 346.3800 Product description : Product details： Product name: Gibberellic acid ( GA3)CAS No. [77-06-5]Mode of action:Acts as a plant growth regulator on account of its physiological and morphological effects in extremely low concentrations. Translocated. Generally affects only the plant parts above the soil surfaceUSES:Has a variety of applications, e.g. to improve fruit setting of clementines and pears (especially William pears): to loosen and elongate clusters and increase berry size in grapes: to control fiuit maturity by delaying development of the yellow colour in lemons; to reduce rind stain and retard rind ageing in navel oranges: to counteract the effects of cherry yellows virus diseases in sour cherries: to produce uniform seedling growth in rice; to promote elongation of winter celery crop: to induce uniform bolting and increase seed production in lettuce for seed; to break dormancy and stimulate sprouting in seed potatoes; to extend the picking season by hastening maturity in artichokes; to increase the yield in forced rhubarb: to increase the malting quality of barley; to produce brighter-coloured, firmer fruit, and to increase the size of sweet cherries; to increase yields and aid harvesting of hops; to reduce internal browning and increase yields of Italian prunes; to increase fruit set and yields of tangelos and tangerines; to improve fruit setting in blueberries; to advance flowering and increase the yield of strawberries; and also a variety of applications on ornamentals. Application rates up to 80 g/a per application, depending on desired effect.Crop:cotton, cucumber , eggplant, grape, pear, celery, spinach, amaranth, lettuce, barley, potato, pea, dolichos lablab l, water melon, citrus lemon, banana, orange, rice, cucumber, strawberryFormulation:90%TC, 10% soluble tablet 20%soluble tabletSpecification of Gibberellic Acid A3 TCItemsStandardAppearanceWhite odorless powderContent of Gibberellins Acid A3(ug/mg)≥900Loss on drying (%)≤0.50Rotation 〔α〕20D≥+80°Color of Solution （2：100methanolClear and ColorlessFineness( trough 40 Mesh)≥95%Specification of GA3 10% Water Soluble TabletsItemsStandardAppearanceWhite or almost white TabletsContent of Gibberellins Acid A3(%)≥10.0Tablet Weight (g/piece)10.00±0.25pH5.0~7.0Dissolving time(min)≤13Test in wet sieve (pass 75 um sieve)≥98Bubble up after a minute≤20Powder and debris≤2Solubility and Stablity (pass 75 um sieve)After 5 min≤5After 18 hour≤1Specification of GA3 20% Water Soluble TabletsItemsStandardAppearanceWhite or almost white TabletsContent of Gibberellins Acid A3(%)≥20.0Tablet Weight (g/piece)5.00±0.25pH5.0~7.5Dissolving time(min)≤13Test in wet sieve (pass 75 um sieve)≥98Bubble up after a minute≤20Powder and debris≤2Solubility and Stablity (pass 75 um sieve)After 5 min≤5After 18 hour≤1Synonyms : 2,4a,7-Trihydroxy-1-methyl-8-methylenegibb-3-ene-1,10-dicarboxylic acid 1,4a-lacto;Gibberellic acid GA-3;(3S,3aR,4S,4aR,7S,9aR,9bR,12S)-7,12-dihydroxy-3-methyl-6-methylene-2-oxoperhydro-4a,7-methano-9b,13-propenoazuleno[1,2-b]furan-4-carboxylic acid;Gibberellic Acid (1.06020);Gibberellic Acid A3;Gibberellin Acid;GA3;(1S,2S,4aR,4bR,7S,9aS,10S,10aR)-2,7-dihydroxy-1-methyl-8-methylidene-13-oxo-1,2,4b,5,6,7,8,9,10,10a-decahydro-4a,1-(epoxymethano)-7,9a-methanobenzo[a]azulene-10-carboxylic acid;(2S,4aR,4bR,9aS,10S,10aR)-2,7-dihydroxy-1-methyl-8-methylidene-13-oxo-1,2,4b,5,6,7,8,9,10,10a-decahydro-4a,1-(epoxymethano)-7,9a-methanobenzo[a]azulene-10-carboxylic acid;(2S,4aR,4bR,7S,9aS,10S,10aR)-2,7-dihydroxy-1-methyl-8-methylidene-13-oxo-1,2,4b,5,6,7,8,9,10,10a-decahydro-4a,1-(epoxymethano)-7,9a-methanobenzo[a]azulene-10-carboxylic acid;2,7-dihydroxy-1-methyl-8-methylidene-13-oxo-1,2,4b,5,6,7,8,9,10,10a-decahydro-4a,1-(epoxymethano)-7,9a-methanobenzo[a]azulene-10-carboxylic acid;(1R,2R,4aS,4bS,7R,9aR,10S,10aS)-2,7-dihydroxy-1-methyl-8-methylidene-13-oxo-1,2,4b,5,6,7,8,9,10,10a-decahydro-4a,1-(epoxymethano)-7,9a-methanobenzo[a]azulene-10-carboxylic acid;(1S,2S,4aR,4bR,7S,9aS,10S,10aR)-2,7-dihydroxy-1-methyl-8-methylidene-13-oxododecahydro-4a,1-(epoxymethano)-7,9a-methanobenzo[a]azulene-10-carboxylic acid; Molecular Structure :
