Description

Methyl-D1 Alcohol CAS NO 4206-31-9 is a deuterated isotopologue of methanol, where one hydrogen atom is replaced by deuterium, a stable hydrogen isotope. This isotopic labeling is critical for applications requiring precise molecular tracking and reduced interference in spectroscopic analysis. It is an essential reagent for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors who require high-purity deuterated solvents for NMR spectroscopy, reaction mechanism studies, and the synthesis of labeled compounds.

Application

• NMR Spectroscopy: Used as a deuterated solvent for proton NMR, providing a lock signal and minimizing solvent interference in spectral analysis.
• Isotopic Labeling & Tracer Studies: Serves as a key precursor in the synthesis of deuterium-labeled pharmaceuticals and agrochemicals for metabolic and pharmacokinetic research.
• Organic Synthesis: Employed as a specialized reagent in reactions where deuterium incorporation is desired, such as in mechanistic studies or to alter chemical properties.
• Analytical Chemistry: Utilized as a standard or solvent in mass spectrometry and other analytical techniques to improve method sensitivity and accuracy.
• Materials Science: Used in the research and development of organic light-emitting diodes (OLEDs) and other electronic materials where deuterium can enhance stability and performance.
• Catalysis Research: Acts as a probe molecule in studies of reaction mechanisms and catalyst performance in hydrogenation and other processes.

Quality Control

Our Methyl-D1 Alcohol is produced and tested to meet the exacting standards required for research and synthesis. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing key parameters such as isotopic purity (D atom %), chemical purity by GC, water content, and NMR conformity. We adhere to a rigorous quality management system to ensure batch-to-batch consistency and reliability for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Due to its highly volatile nature, ensure containers are kept upright and sealed when not in use. Recommended storage temperature is 2-8°C to maintain optimal stability and isotopic integrity.
