Environmental Fate and Toxicity

Tulathromycin is a white to off-white solid that exists in anhydrous, monohydrate and sesquihydrate forms. It is soluble in most organic solvents and is highly soluble in water below pH of 8 (400g/L) and still at pH 9 (19 g/L). The pKa values of 8.49, 9.28 and 9.80 indicate that, except in alkaline solution or soil -- Tulathromycin is likely to be ionized and to be relatively mobile.
