Description

Benzyl-α-13C Chloride is a stable isotope-labeled organic building block, specifically chloromethylbenzene with a carbon-13 atom at the benzylic alpha position. This precise labeling is critical for creating isotopically enriched compounds used in advanced analytical and research applications. It is an essential reagent for scientists and manufacturers in the pharmaceutical, agrochemical, and material science sectors who require high-fidelity tracers for metabolic studies, reaction mechanism elucidation, and internal standards for quantitative mass spectrometry.

Application

• Pharmaceutical Research & Development: Synthesis of carbon-13 labeled drug candidates and metabolites for pharmacokinetic (PK), pharmacodynamic (PD), and absorption, distribution, metabolism, and excretion (ADME) studies.
• Analytical Chemistry: Preparation of internal standards for accurate quantification via Gas Chromatography-Mass Spectrometry (GC-MS) and Liquid Chromatography-Mass Spectrometry (LC-MS), enhancing method precision and reliability.
• Mechanistic Studies: Serving as a tracer in chemical reaction pathways to investigate mechanisms, particularly in nucleophilic substitution and Friedel-Crafts alkylation reactions.
• Agrochemical Development: Incorporation into labeled pesticide or herbicide molecules to study environmental fate, degradation pathways, and bioaccumulation.
• Material Science: Potential use in the synthesis of labeled polymers or advanced organic materials for structural and dynamic analysis using spectroscopic techniques.
• Diagnostic Agent Synthesis: Building block for developing isotopically labeled contrast agents or probes used in advanced imaging techniques.

Quality Control

Every batch of Benzyl-α-13C Chloride is produced and analyzed under strict quality management protocols. We ensure high chemical and isotopic purity through advanced analytical techniques, including NMR, GC-MS, and HPLC. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing assay, isotopic enrichment, and impurity profiles to meet the stringent requirements of research and regulatory applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic and moisture-sensitive nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Keep away from strong bases and incompatible materials.
