Methanol ACS Reagent Grade

Product Overview

Methanol ACS Reagent Grade (CAS 67-56-1), also known as Methyl Alcohol, Wood Alcohol, or MeOH, is a high-purity, volatile colorless liquid widely utilized in industrial and analytical applications. Manufactured to meet or exceed the specifications set by the American Chemical Society, this solvent ensures minimal interference in critical workflows. Its low water content, controlled acidity, and minimal residue make it the standard choice for high-performance liquid chromatography (HPLC), UV-Vis spectroscopy, and fine chemical synthesis.

This product is formulated for consistency, ensuring reliable baselines and reproducible retention times in chromatographic separations. It serves as a versatile solvent for extraction processes and a reactant in the manufacturing of formaldehyde, acetic acid, and various intermediates. Available in packaging ranging from single gallons to 330-gallon totes, it supports operations from bench-scale research to full-scale production.

• Chemical Synthesis: Acts as a reactant and solvent in the production of esters, methylamines, and formaldehyde.
• Solvent Extraction: Effective medium for extracting organic compounds in industrial processing.
• Laboratory Reagent: Utilized for general purpose cleaning of glassware and equipment in analytical environments.
• Paint and Coating Formulations: Functions as a solvent for specific lacquers, inks, and adhesives requiring high evaporation rates.

Safety and Handling

Methanol is a highly flammable liquid and vapor (Category 2). It is toxic if swallowed, in contact with skin, or if inhaled. Operations involving Methanol ACS Reagent Grade must be conducted in well-ventilated areas, utilizing explosion-proof equipment. Appropriate Personal Protective Equipment (PPE), including solvent-resistant gloves, safety goggles, and face shields, is mandatory.

Store in a cool, dry, well-ventilated place away from heat, sparks, open flames, and incompatible materials such as strong oxidizers and acids. Keep containers tightly closed when not in use. Refer to the Safety Data Sheet (SDS) for detailed safety, spill response, and disposal guidelines tailored to industrial use.

Benefits

Regulatory Compliance: Meets strict ACS specifications for use in regulated analytical environments.
High Purity Profile: Low trace metals and aldehyde content prevent interference in sensitive instrumentation.
Scalable Supply: Stocked in sizes from 1 Quart bottles to 330 Gallon totes to support diverse operational needs.
