Description

Propanethiol-Sd CAS NO 64071-73-4 is a specialized, deuterium-labeled analog of propanethiol, a volatile organosulfur compound. This stable isotope-labeled material is critical for applications requiring precise analytical tracking and internal standardization, particularly in mass spectrometry. It is an essential reagent for researchers and manufacturers in the pharmaceutical, agrochemical, and environmental science sectors who require high-fidelity isotopic markers for metabolic studies, reaction mechanism elucidation, and advanced material synthesis.

Application

• Internal Standard for Mass Spectrometry (MS): Used as a quantitative reference standard in GC-MS and LC-MS analyses to ensure accuracy in the measurement of propanethiol and related compounds.
• Metabolic Pathway Tracing: Employed in pharmaceutical and biochemical research to track the fate of sulfur-containing molecules in biological systems using isotope-ratio monitoring.
• Reaction Mechanism Studies: Serves as a deuterium-labeled probe in synthetic organic chemistry to investigate reaction kinetics, intermediates, and pathways.
• Polymer and Material Science: Acts as a chain-transfer agent or modifying agent in the synthesis of specialized polymers where isotopic labeling is required for material characterization.
• Environmental Analysis: Utilized as a labeled standard for the detection and quantification of volatile sulfur compounds in air, water, and soil samples.
• Flavor and Fragrance Research: Applied in the study of sulfur-containing aroma compounds, allowing for precise differentiation between natural and synthetic origins or tracking degradation products.

Quality Control

Every batch of Propanethiol-Sd is produced and analyzed under strict quality management protocols to ensure isotopic purity, chemical purity, and batch-to-batch consistency essential for research and analytical applications. Our products undergo rigorous quality testing, including NMR and mass spectrometry, to ensure compliance with customer specifications. Certificates of Analysis (COA) detailing isotopic enrichment (e.g., D atom %), chemical purity, and solvent residues are provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place, away from heat, sparks, and open flames. Due to its highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation and moisture ingress. Recommended long-term storage temperature is 2-8°C. Keep away from strong oxidizing agents.
