Properties: 3-hydroxy-1-propyl sulfonic acid is a solid, the common physical form is colorless crystal or powder. It is soluble in water and has an acidic pH. It is a weak acid and can be involved in acid-base reactions. It has antibacterial properties and can be used to inhibit the growth of bacteria and fungi.

Use: 3-hydroxy-1-propyl sulfonic acid has a wide range of applications. It is also used in agriculture as an ingredient in pesticides and herbicides.

1. Chemical synthesis applications

- Catalyst or intermediate:

Sulfonic acid groups give it a strong acidity, which can be used as an acid catalyst in organic synthesis or participate in sulfonation reactions to synthesize more complex sulfonic acid derivatives.

- Surfactant precursors:

The polarity of the hydroxyl and sulfonic groups makes them possible for the preparation of amphoteric surfactants suitable for specific industrial cleaning agents or emulsifiers (further modified in conjunction with long carbon chain structures).

- Agriculture

As an ingredient in pesticides and herbicides.

 

2. Electroplating and metal treatment

- Plating additives:

As a complexing agent to stabilize metal ions (such as nickel, copper), improve coating uniformity and gloss, reduce electrode corrosion.

 

3. Water treatment

- Corrosion inhibitor or scale inhibitor:

By chelating calcium and magnesium plasma, it prevents scale formation and protects metal pipes from corrosion.

 

4. The field of medicine

- Drug intermediates:

It may be used in the synthesis of drugs containing sulfonic acid groups (such as antibiotics or antiviral agents), where the hydroxyl group enhances water solubility to improve bioavailability.

- Local drug carrier:

The strong polarity of sulfonic acid group may be used as excipients in transdermal drug delivery systems.

 

5. Polymer materials

- Functional monomer:

Involved in the synthesis of polymers with hydrophilic properties (such as ion exchange resins or hydrogels) for the separation of membranes or water-absorbing materials.

 

6. Laboratory reagents

- Buffer components:

Hydroxyl groups bound to sulfonic acid groups may be used in biochemical experimental buffer systems in specific pH ranges.

 

Matters needing attention

Exposure to 3-hydroxy-1-propyl sulfonic acid may irritate the skin and eyes, and appropriate personal protective equipment such as gloves and goggles should be worn when using it. During storage and handling, contact with strong oxidants and high temperature conditions should be avoided to avoid the occurrence of dangerous situations. In case of contact with 3-hydroxy-1-propyl sulfonic acid, immediately flush the affected area with plenty of water and seek medical attention.
