Buy 1,4-Butanediol (BDO) | High-Purity Industrial & Chemical Intermediate

Product Overview

1,4-Butanediol (BDO) is a high-grade, colorless, and viscous liquid primary alcohol widely used across global chemical manufacturing, polymer production, and specialty solvent applications. Serving as a crucial chemical intermediate, our premium BDO ($\ge 99.5\%$ purity) offers superior batch consistency, low moisture content, and outstanding reactivity for industrial synthesis.

Whether utilized in the production of polyurethanes, thermoplastic elastomers, polyester resins, or specialty chemical derivatives, our 1,4-Butanediol meets demanding international quality and safety standards.

Technical Specifications & Chemical Properties

Key Industrial Applications

1. Polyurethane Manufacturing: Works as an effective chain extender in the production of thermoplastic polyurethanes (TPU), cast elastomers, reaction injection molding (RIM) parts, and synthetic leather coatings.

2. Polyester & Polymer Resins: Acts as a key monomer in synthesizing Polybutylene Terephthalate (PBT), a high-performance engineering plastic valued for automotive and electrical applications.

3. Specialty Solvents & Intermediates: Serves as a vital chemical precursor for synthesizing $\gamma$-butyrolactone (GBL), tetrahydrofuran (THF), and N-methyl-2-pyrrolidone (NMP).

4. Coatings, Adhesives & Sealants: Enhances flexibility, thermal stability, and mechanical strength in polyurethane adhesives and industrial surface coatings.

Packaging, Storage & Handling Guidelines

• Available Packaging Units:

  • 200 kg HDPE / Steel Drums (UN-approved, factory-sealed)

  • 1,000 L Intermediate Bulk Containers (IBC Totes)

  • Bulk ISO Tank Containers

• Storage Conditions: Store in tightly closed containers in a dry, well-ventilated space between 15∘C and 30∘C. Keep away from direct sunlight, open flames, strong oxidizing agents, and strong acids.

• Handling Note on Solidification: BDO has a natural freezing point of 20.1∘C. Exposure to cool temperatures during transit or storage may cause it to solidify into a waxy white mass. This is a physical change and does not affect product purity. To return BDO to liquid form, gently warm the sealed container in a warm water bath (35∘C−45∘C) before use.

Frequently Asked Questions

Is 1,4-Butanediol (BDO) supplied as a liquid or a powder?

1,4-Butanediol is supplied as a viscous liquid at standard room temperature. Because its freezing point is 20.1∘C(68.2∘F), it can solidify into a waxy white solid in colder weather or unheated storage environments. Gently warming the container melts it back into its liquid state without impacting chemical quality.

What chemical category does 1,4-Butanediol fall under?

1,4-Butanediol belongs to the chemical category of Diols (also known as Glycols or Alkanediols). It is a primary aliphatic alcohol containing two hydroxyl groups ($-\text{OH}$) located at opposite ends of a four-carbon alkane chain.

Is 1,4-Butanediol considered hazardous for transport?

In pure form under standard international transport regulations (IMDG, ICAO/IATA, and US DOT), 1,4-Butanediol is not classified as a dangerous/hazardous good for transport. However, it is shipped in UN-rated leak-proof containers accompanied by a full Safety Data Sheet (SDS) and Certificate of Analysis (COA).

What regulatory requirements apply when importing BDO internationally?

Because BDO can serve as a controlled chemical precursor in several jurisdictions, international importers must adhere to local chemical control regulations. For example, importing BDO into Australia requires registration with AICIS and an approved Import Permit from the Australian Office of Drug Control (ODC), along with an End-User Declaration (EUD).

What is the typical Minimum Order Quantity (MOQ) for commercial BDO?

Standard industrial suppliers typically provide BDO starting at a minimum order quantity of 1 Drum (200 kg / ~55 Gallons) or 1,000 L IBC Totes. Laboratory/analytical reagent suppliers offer smaller volumes (1L) for research and pilot testing purposes.
