In the realm of scientific research and chemical analysis, precision and reliability are paramount. Methanol, identified by its CAS number 67-56-1, is a workhorse chemical that consistently meets these demands. As a Methanol laboratory chemical, its unique properties make it indispensable for a wide array of analytical techniques and experimental procedures.

Methanol's utility in analytical chemistry stems from its exceptional solvency and its low UV cutoff. In High-Performance Liquid Chromatography (HPLC), Methanol is frequently employed as a mobile phase component. Its polarity and ability to dissolve a broad spectrum of organic compounds facilitate the separation and detection of analytes in complex mixtures. The low UV cutoff of Methanol is particularly advantageous in UV/VIS spectroscopy, where it minimizes interference and allows for more accurate quantification of samples, especially in the lower UV range.

For Nuclear Magnetic Resonance (NMR) spectroscopy, Methanol serves as a common deuterated solvent. Deuterated Methanol (CH3OD) ensures that the solvent signal does not overwhelm the signals from the analyte, providing clear and interpretable NMR spectra. This is crucial for structural elucidation and purity determination of synthesized compounds.

Beyond these specific techniques, Methanol's general solvency makes it a go-to solvent for sample preparation, dilution, and cleaning of laboratory glassware and equipment. Its ability to dissolve many organic residues efficiently contributes to maintaining a clean and contamination-free laboratory environment, which is essential for reproducible experimental results.

However, the effectiveness of Methanol in the lab is also closely tied to its purity and safe handling. Laboratory-grade Methanol is typically available in high purity, free from contaminants that could interfere with sensitive analytical measurements. Due to its flammability and toxicity, stringent safety protocols must be followed, including working in well-ventilated areas like fume hoods, using appropriate personal protective equipment (PPE), and proper storage away from ignition sources.

In essence, Methanol (CAS 67-56-1) is a vital component of the modern laboratory. Its consistent performance as a solvent and its specific analytical advantages make it a critical reagent for researchers and analysts across disciplines. Understanding its properties and adhering to safe handling practices ensures that this versatile chemical continues to contribute to scientific advancement.
