4 Pharmacology and Biochemistry
4.1 Absorption, Distribution and Excretion

Cyanuric acid, when given to rats, was rapidly excreted in an unchanged form.

Kearney, P.C., and D. D. Kaufman (eds.) Herbicides: Chemistry, Degredation and Mode of Action. Volumes 1 and 2. 2nd ed. New York: Marcel Dekker, Inc., 1975., p. 174


4.2 Metabolism/Metabolites

(14)C-Labeled cyanuric acid...liberated 13.2 & 7.9% of absorbed radioactivity as (14)CO2 from corn & alfalfa, respectively /after an uptake period lasting from 4 days to 2 wk followed by a depletion period of up to 6 wk. The mechanism involved is triazine ring cleavage./

Approx 90% of the administered dose is reported to be excreted in urine within 12 hr and 99% of this is identified as cyanuric acid.

4.3 Biological Half-Life

90% excreted within 12 hours, and of this 99% is excreted unchanged as cyanuric acid; [HSDB]
