Abstract
Disclosed herein are α-Hydroxy sulfonate aldehydes and synthesis methods therefor. Germicidal compositions including the α-hydroxy sulfonate aldehydes, are also disclosed. In one aspect, a germicidal composition may include a diluent, and a germicidally effective amount of a water-soluble germicidal compound including an aldehyde group and an α-hydroxy sulfonate group. The water-soluble compound may have a solubility of at least 5 (w/v) % in water. In a further aspect, the compound may include 1-hydroxy-3-oxo-2-phenyl-propane-1-sulfonic acid salt, (2-formyl-phenyl)-hydroxy-methane sulfonic acid salt, 1-hydroxy-2-(4-methanesulfonyl-2-nitro-phenyl)-3-oxo-propane-1-sulfonic acid salt, 2-bromo-1-hydroxy-3-oxo-propane-1-sulfonic acid salt, 2-chloro-1-hydroxy-3-oxo-propane-1-sulfonic acid salt, 2-(1-formyl-2-hydroxy-2-sulfo-ethyl)-isonicotinic acid salt, 2-benzooxazol-2-yl-1-hydroxy-3-oxo-propane-1-sulfonic acid salt, or 1-hydroxy-2-(4-methoxy-phenyl)-3-oxo-propane-1-sulfonic acid salt. Germicidal compositions including a mixture of an α-hydroxy sulfonate aldehyde and one or more phthalaldehydes, such as phthalaldehyde, isophthalaldehyde, terephthalaldehyde, or a combination thereof, are…
