Gamma-Butyrolactone (GBL): Industrial Applications, Specifications, and Safe Sourcing

Gamma-Butyrolactone (GBL), identified by CAS number 96-48-0, is a cyclic ester and one of the most widely used industrial solvents in chemical processing, manufacturing, and laboratory environments. With a purity level reaching 99.9% in industrial-grade supply, GBL is prized for its solvent efficiency,

chemical stability, and broad compatibility with organic systems. This article outlines the compound's technical profile, legitimate applications, regulatory considerations, and procurement guidelines for industrial buyers.

Technical Specifications

GBL is a colourless, water-miscible liquid with the following core technical parameters: CAS Number 96-48-0, Density 1.13 g/cm³, Molar Mass 86.09 g/mol, Boiling Point 204°C, Flash Point 98°C, and Purity ≥99.9% (industrial grade). It is classified as non-restricted for standard transport purposes, though regulatory frameworks in specific jurisdictions may impose additional requirements for purchase and import documentation.

Industrial Applications

GBL serves as a high-performance solvent in a diverse range of professional and industrial contexts. Its primary applications include polymer and resin formulation, industrial cleaning and degreasing operations, paint stripping and coating removal, laboratory synthesis and chemical research, and specialized formulation in the pharmaceutical and agrochemical sectors. Its ability to dissolve a wide range of organic and polymer-based materials makes it particularly valuable in manufacturing environments where solvent selectivity and purity are operationally critical.

Regulatory Considerations

While GBL is not classified as a controlled substance under most international chemical frameworks, certain jurisdictions impose import controls, reporting requirements, or end-user verification for commercial purchases. Buyers are advised to confirm local regulatory requirements prior to procurement. Reputable suppliers maintain compliance-ready documentation to facilitate smooth customs clearance across jurisdictions. UAB An Group Export supplies GBL exclusively to verified buyers for confirmed industrial or laboratory end-use.

Procurement and Quality Assurance

When sourcing GBL, industrial buyers should require the following documentation from any supplier: Certificate of Analysis (CoA) confirming purity levels, Safety Data Sheet (SDS) in compliance with GHS standards, batch tracking records, and export compliance documentation. UAB An Group Export provides all required documentation with every shipment and offers bulk pricing for ongoing supply contracts. Minimum order quantities start at 1 litre for sampling and scale upward for production-volume requirements.

Conclusion

Gamma-Butyrolactone remains an essential solvent in modern industrial chemistry, valued for its performance, versatility, and purity. Industrial procurement teams should prioritize documentation-compliant suppliers with verified sourcing chains to ensure consistent quality and regulatory adherence.
