The present invention provides freebase and salt forms, and compositions and methods thereof, useful for treating various conditions in which aldehyde toxicity is implicated in the pathogenesis by the administration of small molecule therapeutics acting as a scavenger for toxic aldehydes.

This disclosure relates to anti-agglomerant low dosage hydrate inhibitors that can inhibit the formation of hydrate agglomerants and/or plugs. Thus, provided herein are carboxy alkyl ester compounds that can be used in hydrate inhibitor compositions and methods of inhibiting formation of hydrate agglomerants in a fluid comprising water, a gas, and optionally a liquid hydrocarbon. Also provided herein are methods of making the carboxy alkyl ester compound.
