Phloroglucin hcl

Phloroglucinol is a weak triprotic acid. The first two pKa's are 8.5 and 8.9. As an enol, phloroglucinol in principle exists in equilibrium with keto tautomers. Evidence for this equilibrium is provided by the formation of the oxime: C6H3(OH)3 + 3 NH2OH → (CH2)3(C=NOH)3 + 3 H2O But it behaves also like a benzenetriol as the three hydroxyl groups can be methylated to give 1,3… WebbAccumulation of lignin, visualized using phloroglucin HCl, was also observed in these tissues. The lack of GS1;2 resulted in reduced accumulation of lignin. Re-introduction into the mutants of OsGS1;2 cDNA under the control of its own promoter successfully restored the outgrowth of tillers and lignin deposition to wild-type levels.
