From the 11th edition Merck Index:
Gibberellic Acid- C19H22O6 mol wt. 346.37
Plant hormone-promotes growth of seedlings-pK 4.0 slightly sol. in
water, freely sol. in methanol,ethanol,acetone,aq solns of NaHCO3
Available as Potassium gibberellate (Gibrel)- White, bulky powder. pH
of 5% soln 5.5-6.5. One gram dissolves in 20 ml water.
More than 60 gibberellins (GAs) are known of which
gibberellin A3 (gibberellic acid) is the most important. GA3 and
mixtures of GA4 and GA7 are available commercially. All gibberellins
are diterpenoid acids based on the gibberellane skeleton containing
the gibbane nucleus.
Other than that, I don't see much else on gibberellic acid. I hope
some of it is useful.
