Product Name – METHANOL SPECIALLY DRIED 99% AR Quantity/Pack Size – 500 ml, 2500 ml Form – Liquid Grade – Analytical Reagent (AR) Application – Solvent, extraction, HPLC, synthesis

Product Overview

METHANOL SPECIALLY DRIED 99% AR is a high-purity, anhydrous solvent designed for critical laboratory applications where moisture contamination must be minimized. This analytical reagent (AR) grade methanol undergoes rigorous drying processes to ensure ultra-low water content, making it suitable for sensitive reactions, chromatography, and spectroscopic analysis. Its exceptional purity (99%) guarantees consistent performance in synthesis, extraction, and sample preparation, eliminating interference from residual impurities. The specially dried formulation enhances stability and reactivity in moisture-sensitive protocols, while its low UV absorbance ensures compatibility with HPLC and UV-Vis spectroscopy. Packaged in airtight, leak-proof containers, this methanol maintains its integrity during storage and transport. Whether used as a reaction medium, cleaning agent, or mobile phase, its reliability and precision make it a staple in research and quality control laboratories.

FAQs

1. What is the difference between specially dried methanol and regular methanol?

Specially dried methanol undergoes additional dehydration steps to achieve ultra-low water content, typically below 0.01%, whereas regular methanol may contain trace moisture that can interfere with sensitive reactions or analyses.

2. Can this methanol be used as a mobile phase in HPLC?

Yes, its 99% purity and low UV absorbance make it highly suitable for HPLC applications, provided it is filtered and degassed before use to prevent column damage or baseline noise.

3. Is this methanol compatible with plastic containers for storage?

While it can be stored in HDPE or PTFE containers short-term, prolonged storage in plastic may risk leaching or permeability. Glass or metal containers with PTFE-lined caps are recommended for long-term storage.

4. What precautions should be taken when handling this solvent?

Always use in a well-ventilated fume hood, wear nitrile gloves and safety goggles, and avoid inhalation or skin contact. Methanol is highly flammable and toxic if ingested or absorbed through the skin.

5. Are there alternatives to specially dried methanol for moisture-sensitive applications?

Ethanol (absolute, 99.9%) or isopropanol (anhydrous) can be alternatives, but their polarity and reactivity differ. For critical applications, specially dried methanol remains the preferred choice due to its balanced properties.
