Product Introduction:

4-Hydroxybenzenesulfonic acid (p-hydroxybenzenesulfonic acid) is an organic sulfonic acid, which means it contains one or more sulfonate groups. These esters are bonded to a hydroxyl group and a benzenesulfonyl group, the compound’s name comes from the number of hydroxyl groups, and its chemical formula is C6H6O4S.

4-Hydroxybenzenesulfonic acid is a white crystalline powder in general state, soluble in water, hot alcohol and glycerin. It has been used as a very important intermediate in the synthesis of many other compounds (such as pesticides, drugs and pharmaceuticals) and in the pharmaceutical industry, and its non-negligible research and commercial value has gradually been discovered.

4-Hydroxybenzenesulfonic acid is often used to synthesize sodium p-hydroxybenzenesulfonate (NaHBSO), a chemical often used in its salt form. It is found in natural sources such as fruits, vegetables, and soybeans.

If p-hydroxybenzenesulfonic acid is inhaled, remove patient to fresh air. In case of skin contact, remove contaminated clothing, rinse skin thoroughly with soap and water, and seek medical attention if discomfort occurs.

Product Usage:

4-Hydroxybenzenesulfonic acid has many uses and applications. Some of these applications include:

Used as an Intermediate

Sodium p-hydroxybenzenesulfonate is a very important intermediate in organic synthesis and pharmaceutical industry, such as: 4-hydroxybenzoic acid, it is the starting material for the manufacture of 4-hydroxybenzoate analgesics, and it is also used in the production of 4-hydroxybenzoic acid. 5-Hydroxynaphthalene sulfonic acid, pyrethrin, 1,3,5-triazine derivatives and other precursors.

4-Hydroxybenzenesulfonic acid is the most important additive in the acid tin plating process, and it also has the effect of acid resin foaming and is the precursor of sulfuric acid. 4-Hydroxybenzenesulfonic acid is usually used as the main raw material for the production of sodium p-hydroxybenzenesulfonate, and it is also a compound used in the production of acrylic polymers (ie polyesters).

used as a Corrosion Inhibitor

4-Hydroxybenzenesulfonic acid is also used as a corrosion inhibitor in pipeline systems for natural gas and water. 4-Hydroxybenzenesulfonic acid can be used as a corrosion inhibitor and water in natural gas pipeline systems. It has the ability to lower the surface tension of water and inhibit corrosion of steel, aluminum, brass and other metals by preventing its surface from further reacting with oxygen in the air.

Use in Other Fields

4-Hydroxybenzenesulfonic acid is also used in the production of other chemicals such as dyes, plastics, resins and coatings.

It is the main ingredient used in the production of first-generation detergents, hydroxybenzenesulfonic acid, sodium dodecylbenzenesulfonate (SDBS) and its salts.

4-Hydroxybenzenesulfonic acid is a versatile reagent. It was originally used as a chemical intermediate in the manufacture of sulfonated alkyl esters, but has found many other uses in organic synthesis.

4-Hydroxybenzenesulfonic Acid Side Effects：

The U.S. Food and Drug Administration (FDA) reports that 4-hydroxybenzenesulfonic acid can cause side effects such as nausea, vomiting, diarrhea, headache, and loss of taste.

The main side effect of 4-hydroxybenzenesulfonic acid is skin irritation, which can lead to ulcers and even death if not handled properly. People allergic to this substance should not accidentally use products containing this substance, as it can be fatal.

Generally speaking, 4-hydroxybenzenesulfonic acid is a chemical used in the manufacture of polyurethane. It is also present in the leaves of some plants. It has many side effects and can cause problems for people with skin allergies, breathing problems, and other health problems.

p-hydroxybenzenesulfonic acid can also cause a rash in people allergic to sulfites.

4-Hydroxybenzenesulfonic acid is also found in some pesticides to kill pests such as aphids and ants, and it is also used as an industrial chemical and cleaner. It has been shown to cause cancer in mice by interfering with the p53 gene, which regulates cell growth.
