Dimethyl-d6-amine

Updated: 2026-07-15

Overview

Dimethyl-d6-amine is a deuterated derivative of dimethylamine, where all hydrogen atoms are replaced by deuterium (D). This isotopic labeling makes it invaluable in nuclear magnetic resonance (NMR) spectroscopy, where it serves as a solvent or internal standard due to its lack of proton interference. It is also used in pharmaceutical research for metabolic studies and as a building block in synthesizing deuterated compounds. The compound is highly volatile and requires careful handling to avoid exposure and contamination.

Physical and Chemical Properties

Dimethyl-d6-amine is a colorless liquid with a density slightly lower than its non-deuterated counterpart. Its boiling point (7°C) and melting point (-92°C) are marginally higher due to isotopic effects. The compound is soluble in water and most organic solvents, including ethanol and ether. Its deuterated structure provides distinct advantages in NMR applications, eliminating background signals from protons. However, it remains flammable and reactive, similar to dimethylamine.

Main Applications

The primary use of dimethyl-d6-amine is in NMR spectroscopy, where it acts as a solvent or reference compound for analyzing molecular structures. Its deuterated form ensures clean spectra without proton noise. In pharmaceuticals, it is employed to synthesize deuterated drugs, which may exhibit improved metabolic stability. Additionally, it serves as a reagent in organic chemistry for isotopic labeling experiments, aiding in reaction mechanism studies.

Safety and Storage

Dimethyl-d6-amine is highly flammable and corrosive, requiring storage in sealed containers under inert gas (e.g., nitrogen) to prevent degradation. It should be kept away from heat sources and oxidizing agents. Personal protective equipment (PPE), including gloves, goggles, and lab coats, is mandatory during handling. Work should be conducted in a fume hood to avoid inhalation of vapors. Spills must be neutralized with acid and cleaned up immediately.

B2B Procurement Guide

When procuring dimethyl-d6-amine, prioritize suppliers with certifications (e.g., ISO 9001) to ensure quality and consistency. Verify the deuterium enrichment level (typically ≥99%) and chemical purity (≥98%) via certificates of analysis. Bulk purchases may offer cost savings, but consider storage limitations due to the compound's volatility. Lead times can vary, so plan orders in advance, especially for high-purity grades. Custom packaging (e.g., ampoules under nitrogen) may be available upon request.
