Gibberellic Acid CAS 77-06-5

What Gibberellic Acid Is

Gibberellic acid (GA3, C₁₉H₂₂O₆) is a gibberellin plant growth regulator sold as technical crystalline powder for soluble products and tablets. It barely dissolves in cold water, so it is predissolved in alcohol or slightly alkaline water and spray mixes are made fresh, not stored. Keep stock sealed, cool, dry and dark. UATChem supplies technical grade lots, with assay on the COA.

Crop, Horticulture and Malting Uses

• Table grapes. Enlarges berries and loosens clusters for larger, better shaped seedless and seeded table grapes.
• Dormancy and germination. Breaks dormancy in potato tubers, strawberry crowns and seeds for earlier, more even sprouting.
• Fruit set and stem growth. Improves flowering and fruit set in citrus, pear, apple and cotton, and elongates stems in sugarcane and leafy crops.
• Malting, breeding and formulation. Synchronizes germination in barley malting, supports tissue culture and seed programs, and is made into soluble powders, granules, liquids, tablets and seed treatment packs.

Typical Specifications

Technical assay and grade are reported on the COA for each lot; the table below identifies the material.

Packaging, Documents and Ordering

• Small lots in aluminium foil bags, with 25 kg fibre drums and woven bags or bulk bags for volume orders; keep every pack sealed, cool, dry and dark, away from alkaline materials, and use opened stock promptly.
• Gibberellic acid is a plant growth regulator used under local agrochemical registration and label rules; wear dust protection, gloves and goggles when weighing and formulating, keep it out of waterways, and each lot ships with COA, TDS and SDS.
• For a quote, UATChem needs the grade, quantity, packing and destination port.

FAQ

Q: How do growers dissolve gibberellic acid?

A: The powder barely dissolves in cold water, so predissolve in alcohol or weak alkaline water, then dilute and spray that day.

Q: What is gibberellic acid used for on crops?

A: It breaks seed and bud dormancy, stretches stems, evens flowering and sets fruit, sizes table grapes and aids barley malting.

Q: What grade and formulations does UATChem supply?

A: UATChem supplies technical grade GA3 powder for soluble powders, granules, liquids and tablets; assay is stated on the COA.
