Description

1-Chlorobutane-D9 is a deuterated isotopologue of 1-chlorobutane, where nine hydrogen atoms are replaced by deuterium, a stable hydrogen isotope. This high isotopic purity makes it an essential internal standard and tracer in quantitative analytical chemistry, particularly for mass spectrometry (MS) and nuclear magnetic resonance (NMR) spectroscopy. It is primarily used by researchers and quality control laboratories in the pharmaceutical, agrochemical, and environmental sectors to ensure accurate and reliable analytical results.

Application

• Internal Standard for GC-MS and LC-MS analysis of volatile organic compounds (VOCs) and chlorinated solvents.
• Deuterated Tracer in metabolic pathway studies and pharmacokinetic research within pharmaceutical development.
• NMR Spectroscopy Solvent for specific experiments requiring deuterated chlorinated solvents or as a chemical shift reference.
• Environmental Analysis as a labeled standard for monitoring and quantifying 1-chlorobutane and related pollutants in air, water, and soil samples.
• Polymer and Material Science research as a probe molecule for studying reaction mechanisms and diffusion processes.
• Forensic and Doping Control analysis, providing the definitive reference needed for high-confidence identification and quantification.

Quality Control

Every batch of 1-Chlorobutane-D9 is produced and tested to meet exacting standards for isotopic and chemical purity. Our quality assurance protocol includes comprehensive analysis by NMR, GC-MS, and IR spectroscopy to confirm identity, isotopic enrichment (typically ≥99 atom % D), and chemical purity. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting all critical specifications to support your regulatory and research requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flame. Due to its highly volatile nature, keep container tightly sealed when not in use. Recommended storage temperature is 2-8°C to maximize stability.
