Description

Benzoyl-13C6 Chloride is a stable isotope-labeled derivative of benzoyl chloride, where all six carbon atoms in the phenyl ring are the carbon-13 (13C) isotope. This compound is an essential reagent in the synthesis of isotopically labeled compounds for advanced analytical applications. It is primarily used by researchers and manufacturers in the pharmaceutical, agrochemical, and analytical chemistry industries who require high-purity, labeled intermediates for quantitative mass spectrometry, metabolic studies, and internal standard development.

Application

• Synthesis of Isotopically Labeled Standards: A key precursor for preparing 13C-labeled internal standards used in Liquid Chromatography-Mass Spectrometry (LC-MS) and Gas Chromatography-Mass Spectrometry (GC-MS) for accurate quantification.
• Pharmaceutical Research & Development: Used in the synthesis of labeled drug candidates and metabolites for pharmacokinetic, pharmacodynamic, and drug metabolism studies (DMPK).
• Environmental and Food Safety Analysis: Enables the production of labeled analogs of pesticides, toxins, or contaminants for use as internal standards in residue analysis, ensuring high accuracy and precision.
• Biochemical Tracing: Facilitates the creation of probes for metabolic pathway analysis and flux studies in biological systems.
• Organic Synthesis Research: Serves as a versatile 13C-labeled building block for introducing a labeled benzoyl group into target molecules for mechanistic or structural elucidation studies.

Quality Control

Our Benzoyl-13C6 Chloride is produced and handled under strict quality protocols to ensure the high chemical and isotopic purity required for sensitive analytical applications. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing parameters such as isotopic enrichment, chemical purity (by NMR and HPLC), and identity confirmation. We adhere to cGMP principles where applicable to support our clients in regulated research and development.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its nature as a strong acid/organic solvent, it should be kept away from moisture, heat, and incompatible materials such as bases, alcohols, and amines. Recommended storage temperature is 2-8°C for long-term stability.
