The solubility of 1-H-tetrazole-1-acetic acid in ethanol, water, methanol, 1-propanol, ethyl acetate, 2-propanol, acetone, and butyl acetate between 283 K and 323 K was measured using a laser monitoring observation technique. Results of these measurements were correlated with a semiempirical equation. For the eight solvents studied, the data are well fitted with a semiempirical equation.
