Description

Methylacetylene-D4 is a deuterated isotopologue of methylacetylene, where four hydrogen atoms are replaced by deuterium, a stable hydrogen isotope. This high-purity labeled compound is essential for advanced research and analytical applications where isotopic tracing is required. It is particularly valuable for scientists and engineers in the pharmaceutical development, materials science, and spectroscopy sectors who require precise molecular probes.

Application

• NMR Spectroscopy: Used as an internal standard or a deuterated solvent shift reference in nuclear magnetic resonance (NMR) analysis.
• Mechanistic Studies: Acts as a tracer in chemical reaction mechanisms to study pathways, kinetics, and isotopic effects.
• Mass Spectrometry: Serves as a calibration standard or a labeled internal standard in GC-MS or LC-MS for quantitative analysis.
• Polymer & Materials Research: Employed in the synthesis and study of deuterated polymers and advanced materials for unique optical or electronic properties.
• Pharmaceutical R&D: Utilized in the development and metabolic studies of deuterated drug compounds, a growing field in medicinal chemistry.
• Catalysis Research: Used to investigate surface reactions and mechanisms in heterogeneous and homogeneous catalysis.

Quality Control

Every batch of Methylacetylene-D4 is produced and analyzed under stringent conditions to ensure the highest isotopic and chemical purity for research applications. Our quality assurance protocol includes verification of deuterium incorporation and assessment of chemical impurities. A comprehensive Certificate of Analysis (COA) detailing isotopic purity (D-enrichment), chemical assay, and identity confirmation is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and gaseous nature under standard conditions, this material is typically supplied in a sealed, pressurized cylinder or ampule. Store in a cool, well-ventilated area, away from heat, sparks, and open flames. The container must be kept upright and secured.
