What is 1-Propanol (CAS 71-23-8)?
1-Propanol, also known as N-propanol, is an organic compound, at standard temperature and pressure, n-propanol is a transparent, colorless liquid with a strong, musty odor similar to rubbing alcohol. It is soluble in water, ethanol, and diethyl ether. It is typically synthesized from ethylene via carbonylation to produce propionaldehyde, followed by reduction.
What are 7 uses for N-Propanol ?
N-Propanol (CAS No. 71-23-8), also known as n-propyl alcohol, 1-propanol, or normal propanol, is an important organic solvent and chemical intermediate. Due to its excellent solvency and chemical stability, n-propanol is widely used in the pharmaceutical, cosmetics, food, agricultural, and industrial sectors.
Solvent Applications
N-propanol can be used directly as an industrial solvent or converted into propyl acetate, which is commonly applied in coatings, printing inks, and cosmetic formulations. In many applications, n-propanol serves as a suitable alternative to ethanol due to its higher boiling point and better solvent balance.
Pharmaceutical Industry
In pharmaceutical manufacturing, n-propanol alcohol is used to produce key intermediates such as n-propylamine, which are further processed into active pharmaceutical ingredients (APIs). It plays a role in the synthesis of drugs including probenecid, sodium valproate, and erythromycin, making it a valuable raw material for pharmaceutical producers.
Paints and Coatings
As a solvent for resins and pigments, n-propanol improves dispersion and dissolution in paint and coating systems. Its controlled evaporation rate contributes to smoother film formation and consistent coating performance.
Cosmetics and Personal Care
In the cosmetics industry, n-propyl alcohol is used as a solvent and preservative aid. It helps maintain formulation stability, supports ingredient compatibility, and extends product shelf life in items such as perfumes, lotions, and skincare products.
Agrochemical Production
N-propanol is used to manufacture agrochemical intermediates such as di-n-propylamine, which is essential for producing herbicides and fungicides including Ametryn and Chlorothalonil-based formulations. It is a key raw material in modern pesticide synthesis.
Food Additives and Preservatives
Esters derived from n-propanol, such as propyl paraben (propyl p-hydroxybenzoate), are widely used as preservatives in food products. These compounds help inhibit microbial growth and extend shelf life when used within regulated limits.
Flavor and Fragrance Synthesis
N-propanol and its derivatives are used in the synthesis of flavors and fragrances, contributing to fruity and floral notes in food, cosmetics, and household chemical products.
