Description

Sodium Benzoylthioethanesulfonate-D4 CAS NO 1189657-00-8 is a high-purity, isotopically labeled derivative of sodium benzoylthioethanesulfonate, where four hydrogen atoms are replaced with deuterium. This deuteration is critical for applications requiring high sensitivity and minimal background interference in analytical techniques. It serves as an essential internal standard or reference material for researchers and quality control laboratories in the pharmaceutical and analytical chemistry sectors, ensuring precise quantification and method validation.

Application

• Primary use as a deuterated internal standard in Liquid Chromatography-Mass Spectrometry (LC-MS) and Gas Chromatography-Mass Spectrometry (GC-MS) for the accurate quantification of its non-deuterated counterpart.
• Critical reference material in pharmaceutical research and development, particularly in pharmacokinetic and metabolic stability studies.
• Essential for method development and validation in analytical laboratories to comply with regulatory guidelines (e.g., FDA, ICH).
• Used in environmental analysis for tracing and quantifying specific sulfonate compounds.
• Application in deuterium labeling studies and mechanistic investigations in organic and medicinal chemistry.
• Potential use in the synthesis of other deuterated fine chemicals and advanced intermediates.

Quality Control

Every batch of Sodium Benzoylthioethanesulfonate-D4 is manufactured and tested under strict quality management systems. We guarantee high chemical purity and isotopic enrichment, supported by comprehensive analytical data including NMR, MS, and HPLC. A Certificate of Analysis (COA) detailing purity, isotopic purity (D-enrichment), and identity is provided with each shipment to ensure traceability and compliance with your research or quality standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider using desiccants.
