About Hemp

Alliance Chemical provides high-purity solvents and specialty chemicals specifically selected for hemp and cannabis extraction, purification, and analytical testing operations. Our products meet the stringent purity requirements demanded by state regulations and laboratory accreditation standards, supporting both commercial-scale extraction facilities and analytical testing laboratories.

Common Applications

  • Ethanol extraction: Primary solvent for cannabinoid and terpene extraction from hemp biomass
  • Hydrocarbon extraction: Butane and propane-based extraction systems for concentrates
  • Winterization processes: Low-temperature ethanol treatment to remove fats, waxes, and lipids
  • Analytical testing: Mobile phase solvents for HPLC potency testing and terpene analysis
  • Residual solvent testing: Reference standards and carrier solvents for GC/MS analysis
  • Post-extraction refinement: Distillation and purification of crude extracts

What We Carry

Our hemp extraction collection features ACS reagent grade and food-grade solvents including ethanol, isopropyl alcohol, hexane, n-heptane, and ethyl acetate. We also supply specialty chemicals like d-limonene (94% food grade) for terpene applications and polyethylene glycol (PEG) for formulation work. All solvents meet or exceed industry purity standards with typical concentrations ranging from 94% to 99.9%.

Available Pack Sizes

Products are available in laboratory quantities from 1-quart bottles up to production volumes including 5-gallon pails, 55-gallon drums, and 275-gallon totes. This flexibility supports everything from R&D testing to commercial extraction operations.

Understanding solvent specifications is critical for hemp applications. Review our full chemical grades guide to select the appropriate grade for your specific process requirements.

Every order includes complete Safety Data Sheets (SDS) and Certificates of Analysis (COA) to support regulatory compliance and quality assurance protocols. We offer 1-2 business day shipping on in-stock items with no minimum order requirements, ensuring you maintain continuous operations.

✓ SDS Included ✓ COA Available ⚡ 1-2 Day Ship Times ★ No Minimum Order

Frequently Asked Questions

What solvents are best for hemp extraction?
The best solvents for hemp extraction depend on your desired end product and equipment. Common choices include ethanol, known for its safety and ease of use, and hydrocarbons like butane or propane, which offer high efficiency in cannabinoid extraction. Alliance Chemical provides high-purity grades of each for both large-scale operations and small-scale testing.
How do I winterize cannabis extracts?
Winterization removes unwanted fats and waxes from cannabis extracts, improving purity and clarity. It typically involves dissolving the extract in ethanol, chilling the solution to sub-zero temperatures, and then filtering out the precipitated lipids. Alliance Chemical offers high-purity ethanol suitable for this process.
What solvents are used for residual solvent analysis?
Residual solvent analysis identifies any remaining solvents in a cannabis extract after processing. Common solvents for this analysis include acetone, acetonitrile, and methanol. Alliance Chemical offers ACS grade solvents for accurate and reliable results in laboratory testing.
What is the difference between denatured and undenatured ethanol?
Undenatured ethanol is pure ethanol, while denatured ethanol has additives that make it unfit for human consumption. Denaturing agents vary, but commonly include isopropyl alcohol or methanol. While undenatured ethanol is preferable for some extractions, denatured ethanol is often used for cleaning and certain processing steps where purity is less critical. Alliance Chemical carries both denatured and undenatured alcohol in various grades.
What is the best way to store solvents safely in a cannabis extraction lab?
Proper solvent storage is crucial for safety. Store solvents in tightly sealed, properly labeled containers in a cool, well-ventilated area away from heat, sparks, and open flames. Flammable solvents should be stored in a designated flammable liquids storage cabinet. Consult the SDS for each chemical and adhere to all local fire codes. Alliance Chemical provides safety data sheets (SDS) for all of our products.
What is ACS grade and why is it important for cannabis testing?
ACS grade refers to chemicals that meet the purity standards set by the American Chemical Society. Using ACS grade chemicals in cannabis testing ensures accurate and reliable results, which is essential for potency testing, residual solvent analysis, and other quality control measures. Alliance Chemical offers a range of ACS grade solvents and reagents for your cannabis testing needs.
What safety precautions should I take when handling solvents for cannabis extraction?
Always wear appropriate personal protective equipment (PPE) such as gloves, eye protection, and a lab coat when handling solvents. Work in a well-ventilated area, preferably under a fume hood, to avoid inhaling vapors. Be aware of the flammability of solvents and avoid any sources of ignition. Always refer to the SDS for specific safety information. Contact Alliance Chemical with any questions about the safe handling of our chemicals.
What solvents can I use to clean my cannabis extraction equipment?
Effective cleaning of cannabis extraction equipment is crucial for preventing contamination and ensuring product quality. Isopropyl alcohol, acetone, and ethanol are frequently used for cleaning due to their solvent properties and ability to remove residues. Always ensure the equipment is thoroughly dry before re-use. Alliance Chemical provides solvents in various grades and sizes for any size cleaning operation.
Is hexane safe for botanical extractions?
Hexane is a highly effective solvent for botanical extraction, but it must be handled with extreme care due to its flammability and potential health hazards. Proper ventilation, PPE, and rigorous residual solvent testing are crucial to ensure product safety. Alliance Chemical offers high-purity hexane and provides guidance on its safe handling and use. We recommend reading all SDS information prior to using any chemical.
How do I dispose of used solvents from cannabis extraction?
Solvent disposal must comply with local, state, and federal regulations. Never pour solvents down the drain or into the environment. Common disposal methods include incineration, recycling, and treatment by a licensed waste disposal facility. Contact Alliance Chemical if you have questions about solvent disposal methods in your area, and check with local regulatory authorities.
