Properties and Usage:
Para-aminobenzoic acid (CAS 150-13-0), referred to as PABA, is commonly used in medicine, cosmetics, industrial chemistry and agriculture.
1. Pharmaceutical field
Vitamin-like substances: PABA is a non-essential component of the vitamin B complex and participates in cell metabolism, especially the synthesis of folic acid.
Pharmaceutical raw materials: As a key intermediate in the production of local anesthetics (such as benzocaine) and sulfonamide antibiotics, it is used in a variety of pharmaceutical preparations.
Skin care: PABA derivatives (such as PABA potassium salt) are used to treat photosensitive dermatitis and vitiligo, and have repair and protective effects.
2. Cosmetics and sunscreens
PABA was once widely used in sunscreens due to its ability to absorb UVB ultraviolet rays. Although modern sunscreens have gradually replaced it, it is still a representative of classic sunscreen ingredients.
3. Industrial and chemical synthesis
Dye industry: PABA is an important intermediate for dyes such as azo dyes and is used in a variety of synthetic processes.
Organic synthesis: Participates in the production of a variety of chemicals, such as benzocaine and folic acid, as an important precursor of high value-added compounds.
4. Agricultural field
PABA is used in the production of plant growth promoters and fungicides, which can significantly increase the yield and disease resistance of crops.
