Melting Point: ~226°C (decomposes)
Solubility in Water: High (~430 g/L at 20°C)
Solubility in Organic Solvents: Slightly soluble in ethanol, insoluble in non-polar solvents
Odor: Odorless
Stability: Stable under standard conditions; hygroscopic
Form: Crystalline powder

Applications
Used in electroplating solutions (e.g., as a brightener in nickel plating)
Applied in laboratory chemistry as a reference sulfonamide compound
Utilized in technical formulations requiring non-reactive organic sulfonates
Sometimes used as a tracer or non-nutritive organic additive in R&D
Applicable in corrosion inhibition systems and specialty cleaners
