Description

1-Butan-D9-Ol CAS NO 25493-17-8 is a deuterated isotopologue of n-butanol, where nine hydrogen atoms are replaced by the stable isotope deuterium. This high isotopic purity makes it an essential internal standard and tracer in advanced analytical chemistry, ensuring precise quantification and eliminating matrix effects. It is a critical material for researchers and quality control laboratories in the pharmaceutical, agrochemical, and environmental sectors requiring high-fidelity mass spectrometry and NMR spectroscopy.

Application

• Internal Standard for Quantitative Analysis: Used in GC-MS and LC-MS methods for the accurate quantification of butanol and related compounds in complex matrices.
• Metabolic Pathway Tracing: Serves as a stable isotopic tracer in pharmacokinetic, metabolic, and biodegradation studies.
• NMR Spectroscopy Solvent & Reagent: Employed as a deuterated solvent for shift referencing or as a labeled reagent in synthetic chemistry to track reaction mechanisms.
• Pharmaceutical Impurity Profiling: Critical for developing and validating analytical methods to identify and quantify process-related impurities.
• Environmental Analysis: Used as a standard in the detection and measurement of volatile organic compounds (VOCs) in air, water, and soil samples.
• Material Science Research: Acts as a labeled precursor in the synthesis of deuterated polymers or liquid crystals for specialized research applications.

Quality Control

Every batch of 1-Butan-D9-Ol is produced and tested under a strict quality management system. We guarantee high isotopic and chemical purity, with specifications typically meeting or exceeding 98 atom % D and 99.0% chemical purity (by GC). Comprehensive testing includes isotopic purity by NMR, chemical assay, and identification. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to ensure full traceability and compliance with your research or quality protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); keep the container tightly sealed under an inert atmosphere if specified to maintain purity and prevent absorption of water or atmospheric contaminants.
