Thiosalicylic acid CAS NO.147-93-3, appearing as a white to light yellow triclinic crystal or white to light yellow solidified form, is soluble in ethanol and glacial acetic acid, and slightly soluble in water. Used for the production of sulfur indigo dyes and also as a reagent for analyzing iron. In the electroplating industry, it is used for anti-corrosion treatment in the production of black metals, as well as a metal surface treatment agent, and as a coloring agent in the ceramic industry.

 

What is the structure of Thiosalicylic acid CAS NO.147-93-3 ?

 Structure is as follows:

What is Thiosalicylic acid CAS NO.147-93-3 ?

The structure of Thiosalicylic acid CAS NO.147-93-3 contains a hydroxyl group (OH) and a thiol group (SH), making it different from salicylic acid (salicylic acid has a similar structure, but it has a hydroxyl group instead of a thiol group). This structure endows thiosalicylic acid with some unique chemical properties, making it play an important role in the fields of skincare and cosmetics

 

What are properties of Thiosalicylic acid CAS NO.147-93-3 ?

Acidity: Thiosalicylic acid is a weak acid that can release hydrogen ions (H+) and form an acidic solution. This makes it used in some skincare products to adjust pH values to ensure the product’s gentleness towards the skin.

 Nucleophilicity: Due to the presence of thiol groups in thiosalicylic acid molecules, it has a certain degree of nucleophilicity and can participate in some nucleophilic substitution reactions. This enables it to play a role in certain chemical synthesis and organic reactions.

Keratin Softening Effect: Thiosalicylic acid can react with proteins in the stratum corneum and has a certain degree of keratin softening effect. This has enabled its application in some exfoliating and exfoliating skincare products.

Antioxidant Properties: Thiosalicylic acid has strong antioxidant properties, which can neutralize free radicals and slow down the oxidation process. This makes it used in skincare products to resist oxidative stress, helping to protect the skin from environmental damage.

Metal Chelation: Due to the thiol group of thiosalicylic acid, it can form chelates with metals and participate in some metal coordination reactions.

 

What are applications of Thiosalicylic acid CAS NO.147-93-3 ?

Chemical Synthesis: Thiosalicylic acid is often used as a reagent in organic synthesis, participating in some nucleophilic substitution reactions and other organic synthesis reactions. The nucleophilic properties of its thiol group enable it to play a role in some organic synthesis reactions.

Curling Agent: Due to its keratin softening properties, thiosalicylic acid is sometimes added to certain curling agents to soften the stratum corneum when changing the shape of hair, making it easier for hair to set.

Metal Corrosion Inhibition: Thiosalicylic acid can be used as an inhibitor of metal corrosion. It can react chemically with the metal surface to form a protective film, slowing down the corrosion rate of the metal

Exfoliation: Thiosalicylic acid can react with proteins in the stratum corneum and has a keratin softening effect. This makes it a common exfoliating ingredient that helps to remove aging keratinocytes, improve uneven skin tone and delicate skin texture.

Antioxidant: Thiosalicylic acid has antioxidant properties, can neutralize free radicals, and slow down the aging process of the skin. Therefore, it is often added to skincare products to help protect the skin from environmental damage.
