Application

El metanol (MeOH) se ha utilizado en los estudios de tejidos embrionarios completos mediante inmunofluorescencia.
Puede utilizarse en los estudios siguientes:
  • Ensayo de unidad de fibroblastos formadora de colonias de células mononucleares de médula ósea.
  • Como disolvente para la preparación de extractos de hifas de Aspergillus para la estimación de la gliotoxina mediante HPLC de fase inversa.
  • Estudios de inmunofluorescencia.
  • Componer el eluente para el aislamiento de nucleótidos y sus productos de decomposición mediante HPLC de fase inversa de par iónico.
El metanol puede utilizarse como una fase móvil en la cromatografía de líquidos de fase inversa.

General description

El metanol es un disolvente orgánico que puede sintetizarse a partir de gas de síntesis en presencia de los catalizadores CuO/AnO/Al2O3. Es un candidato ideal como fuente de hidrógeno en la tecnología de pila de combustible debido a su elevada proporción H/C, su baja propensión a la generación de hollín, su relativamente baja temperatura de reformado y a que existe en estado líquido a temperatura ambiente. En la pila de combustible de alimentación directa de metanol (DMFC), el metanol se oxida con el aire para generar electricidad. Las olefinas (etileno o propileno) formadas a partir del metanol a través del proceso MTO (metanol a olefinas), pueden constituir una alternativa al petróleo y al gas para producir hidrocarburos combustibles.
Se ha comunicado la conversión termoquímica de metanol a hidrocarburos de C2-C10 en presencia de zeolitas con selectividad geométrica. Se ha procesado su oxidación en el sistema catalizador de Ru-Pt mediante adátamos de rutenio.

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. Who do I contact about larger solvent volume needs?

    Email us at labessentials@sial.com or visit Sigma-Aldrich Fine Chemicals for development and manufacturing-scale inquiries: safcglobal@sial.com

  4. How do I know what packaging options are available for a solvent?

    The Solvent Center gives you the ability to review all the specifications associated with our solvent packaging. This includes physical dimensions, closure types, dispensing methods, UN/DOT Rating as well as solvent compatibility. Visit the Solvent Center.

  5. Who do I contact if I need a solvent blend, which you do not carry?

    Email us at labessentials@sial.com. For a complete listing of all our Solvent blends, Visit the Solvent Center

  6. The dispensing of solvents provides some challenges due to the number of container options available. What dispensing options are available for each container?

    The Sigma-Aldrich Solvent Center provides numerous dispensing options for each container type. For a complete listing of all our dispensing options, Visit the Solvent Center.

  7. Which solvent grade should I be using for my application?

    Sigma-Aldrich Solvent Applications Table gives a guideline to common applications and the appropriate solvent grades.  Visit: Solvents

  8. What are the options for drying solvents? 

    Sigma-Aldrich offers a full range of high-purity solvents with extremely low water levels specifically manufactured for moisture sensitive Organic and Biotech applications.  Sigma-Aldrich also carries various drying agents such as molecular sieves, which are typically compatible with organic solvents.

  9. What apparatus do you recommend for HPLC solvent filtration?

    The Sigma-Aldrich Vacuum Filtration Assembly gives you all the components you need including: funnel top, fritted glass funnel support, filtration flask, aluminum clamp, and silicone stopper.  The Acrodisc Syringe Filters offer high quality filtration for analytical samples, certified for HPLC to ensure low extractable and available in a broad range of membranes to meet sample compatibility requirements.

  10. Can you recommend a Solvent Extractor for organics from aqueous solution?

    Solvent extractors are often used for the quantitative extraction of organics from aqueous solutions and separations in immunoassays. The MIXXOR system has been applied successfully in many laboratory solvent extraction operations and is ideal for the rapid screening of alternative solvents for specific extraction problems.

  11. Why on occasion does Product 34860, Methanol, have an unusual odor? Does it affect the product purity or performance?

    Industry research has indicated that unusual odors in methanol are a common problem and stem from low - level mercaptans and / or amines found in the natural gas raw materials used in production. Odors from these types of compounds can be noticeable at low part per million (ppm) levels and have not been shown to have any negative impact on product performance at these concentrations.

  12. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page. You can contact any of our Customer Sales and Service offices to receive a quote.  USA customers:  1-800-325-3010 or view local office numbers.
