Description

1-Butane-D9-Thiol is a deuterated analog of n-butanethiol, where nine hydrogen atoms are replaced by deuterium, making it a valuable isotopically labeled compound. This high isotopic purity is critical for applications requiring precise molecular tracking and minimal spectral interference. It is primarily utilized by researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors for use as an internal standard, a tracer in metabolic studies, and a building block in deuterated synthesis.

Application

• Internal Standard for GC-MS and LC-MS analysis in analytical laboratories.
• Tracer compound in pharmacokinetic and metabolic pathway research.
• Deuterated building block for the synthesis of more complex labeled pharmaceuticals and agrochemicals.
• Use in mechanistic studies and reaction kinetics where hydrogen/deuterium isotope effects are investigated.
• Component in the development of organic electronic materials requiring specific isotopic profiles.
• Reference material for spectroscopic calibration and method validation.

Quality Control

Our 1-Butane-D9-Thiol is produced under strict quality systems to ensure high chemical and isotopic purity. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing key parameters such as isotopic enrichment (D-atom %), chemical purity by GC, and identity confirmation. We support compliance with relevant research and development standards.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C to minimize oxidation and volatility. Keep away from heat, sparks, and open flames. The container should be stored in a cool, well-ventilated place.
