Unveiling the Potential of 1,4-Butanediol (CAS 110-63-4): A Versatile Chemical Compound

1,4-Butanediol (CAS 110-63-4) may not be a household name, but this versatile chemical compound plays a significant role in various industries. From its chemistry to its applications and even safety considerations, we’re about to dive deep into the world of 1,4-Butanediol.

The Basics of 1,4-Butanediol

1,4-Butanediol, often referred to as 1,4-BDO or simply BDO, is a colorless, odorless, and viscous liquid. Its chemical formula is C4H10O2, and it’s classified as a diol or glycol, a type of organic compound containing two hydroxyl (OH) groups. This specific arrangement of atoms lends it several intriguing properties and applications.

Chemical Structure and Properties

At the heart of 1,4-Butanediol’s versatility is its chemical structure. The compound consists of a chain of four carbon atoms, each bonded to two hydrogen atoms and one hydroxyl group. The presence of two hydroxyl groups makes it a diol, allowing it to participate in various chemical reactions.

1,4-Butanediol is a highly polar compound, which means it’s soluble in water and many organic solvents. Its boiling point is around 235°C (455°F), and it’s known for its low volatility. This makes it suitable for numerous industrial applications.

Applications of 1,4-Butanediol

1,4-Butanediol finds its utility in a wide range of industries, thanks to its unique properties:

Chemical Manufacturing: In the chemical industry, BDO serves as a precursor for the production of various valuable compounds, such as tetrahydrofuran (THF), gamma-butyrolactone (GBL), and polybutylene terephthalate (PBT), which are used in the production of plastics, resins, and more.

Pharmaceuticals: It plays a vital role in the synthesis of pharmaceuticals and as a solvent in drug formulations. Its use in medicine highlights its safety and purity standards.

Cosmetics and Personal Care: BDO is also found in personal care products, such as moisturizers and creams, due to its ability to improve the texture and consistency of formulations.

Industrial Cleaning: BDO is used as a cleaning agent in various industrial processes due to its excellent solvency properties.

Solvents: It acts as a versatile solvent in both industrial and laboratory settings, where its low volatility is a significant advantage.

Textile and Leather Processing: BDO is used in dyeing and finishing processes for textiles and leather.

Safety Considerations

Safety is paramount in the handling of 1,4-Butanediol. It’s generally recognized as safe when used in compliance with relevant regulations and guidelines. However, like any chemical substance, it must be handled with care. Proper storage, transportation, and personal protective equipment are essential when working with BDO. Its low volatility reduces the risk of inhalation exposure, but skin contact and ingestion should be avoided.

Regulation and Control

As with many chemicals, governments and international organizations have established regulations and controls for 1,4-Butanediol to ensure its safe use. Companies that produce, distribute, or use BDO must adhere to these regulations to protect both workers and the environment.


1,4-Butanediol (CAS 110-63-4) may not be a household name, but it’s a vital ingredient in various industries. From its role in chemical manufacturing to its presence in pharmaceuticals, cosmetics, and beyond, BDO is a versatile and essential compound. Its unique properties, safety considerations, and regulatory controls make it a critical component of modern industry. So, the next time you use a pharmaceutical product or a plastic item, remember that 1,4-Butanediol might have played a significant role in its production.
