Sodium 4-Hydroxybenzenesulfonate TCI P0105

Sodium 4-Hydroxybenzenesulfonate from TCI (product code P0105), also known as sodium p-phenolsulfonate, is the sodium salt of 4-hydroxybenzenesulfonic acid. The compound has a phenolic hydroxyl group and a sulfonate group that has been neutralized as the sodium salt. In the laboratory it serves as a non-heterocyclic building block and as an intermediate in the synthesis of dyes, surfactants, and polymers. It is also used as an additive in electroplating research and in solution formulation work, which makes it a useful reagent across several areas of chemistry.

Researchers choose this compound because it supplies a sulfonated phenol framework as a salt, which is much easier and safer to handle than the free acid. It is typically a solid, so it can be weighed accurately, and it dissolves well in water. The phenolic hydroxyl group stays available for reactions such as etherification, esterification, or condensation. The sulfonate group gives the final product water solubility, a property that matters in dye and surfactant design. Together, these features let chemists add both reactivity and hydrophilicity to a target molecule in one step.

In Indonesia, this salt is useful to organic chemistry, polymer chemistry, and surfactant research laboratories, and to groups developing metal plating processes, in universities and in industry. Researchers who need a reliable source of a sulfonated phenolic group for synthesis or formulation can use this TCI reagent as a consistent starting material. It fits teaching laboratories, academic research projects, and industrial development work where reproducible results and convenient handling matter.

• Dye synthesis: the sulfonate group gives the resulting dye molecules water solubility, while the phenolic hydroxyl group provides a reactive site for building the chromophore structure.
• Surfactant research: the compound has a hydrophilic sulfonate head and a modifiable phenolic group, so it is a practical starting material for designing water-soluble surface-active agents.
• Polymer chemistry: the phenolic hydroxyl group can take part in condensation reactions, so the sulfonated aromatic unit can be built into polymers to change their solubility and other properties.
• Electroplating research: the compound is used as an additive in plating bath studies, where its good water solubility helps it disperse evenly through aqueous electrolyte solutions.
• General organic synthesis: as a non-heterocyclic building block, it allows etherification and esterification at the phenolic group while keeping the sulfonate salt functionality intact.

Store Sodium 4-Hydroxybenzenesulfonate in its original, tightly sealed container in a cool, dry, well-ventilated area, away from direct sunlight, moisture, and incompatible materials such as strong oxidizing agents. Reseal the container promptly after each use so the solid does not absorb moisture. Wear standard laboratory protective equipment when handling it, including safety glasses, gloves, and a lab coat. Avoid creating or breathing in dust, and weigh the material in a well-ventilated area or under local exhaust. Wash your hands thoroughly after handling. Always check the supplier's Safety Data Sheet for full hazard information, first-aid measures, and disposal guidance, and follow your institution's chemical safety procedures.
