Delta(9)-tetrahydrocannabinolic acid is a diterpenoid that is 6a,7,8,10a-tetrahydro-6H-benzo[c]chromene substituted at position 1 by a hydroxy group, positions 6, 6 and 9 by methyl groups and at position 3 by a pentyl group. A biosynthetic precursor to 9-tetrahydrocannabinol, the principal psychoactive constituent of the cannabis plant. It has a role as a metabolite, a biomarker, a neuroprotective agent and an anti-inflammatory agent. It is a diterpenoid, a polyketide, a hydroxy monocarboxylic acid, a benzochromene and a phytocannabinoid. It is a conjugate acid of a Delta(9)-tetrahydrocannabinolate.
