Description

n-(α,α-Dimethylbenzyl)Benzenesulfonamide-13C6 is a stable isotope-labeled analog of a benzenesulfonamide derivative, where six carbon atoms are replaced with the carbon-13 isotope. This compound is specifically designed for use as an internal standard in quantitative mass spectrometry, providing unmatched accuracy and reliability for analytical measurements. It is an essential tool for researchers and quality control laboratories in the pharmaceutical, agrochemical, and environmental testing industries who require precise quantification of the unlabeled parent compound or its metabolites.

Application

• Quantitative Mass Spectrometry (LC-MS/MS, GC-MS): Serves as a critical internal standard for the accurate quantification of n-(α,α-Dimethylbenzyl)Benzenesulfonamide in complex biological and environmental matrices.
• Pharmacokinetic and Metabolite Studies: Enables precise tracking of drug absorption, distribution, metabolism, and excretion (ADME) in pharmaceutical R&D.
• Environmental Fate Analysis: Used to monitor the degradation, transformation, and concentration of sulfonamide-based compounds in environmental samples.
• Agrochemical Residue Testing: Facilitates the accurate measurement of pesticide or herbicide residues in food and crop samples to ensure regulatory compliance.
• Clinical Diagnostics and Biomarker Validation: Supports the development and validation of assays for disease biomarkers in clinical research.
• Method Development and Validation: Essential for developing robust, reproducible, and regulatory-compliant analytical methods in contract research organizations (CROs).

Quality Control

Every batch of n-(α,α-Dimethylbenzyl)Benzenesulfonamide-13C6 is manufactured and analyzed under strict quality systems to ensure the highest isotopic and chemical purity for trace analysis. Our products undergo rigorous quality testing, including NMR and mass spectrometry, to confirm isotopic enrichment and chemical identity. Certificates of Analysis (COA) detailing lot-specific data for isotopic purity, chemical purity, and solvent content are provided with each shipment.

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 material is hygroscopic (moisture-sensitive) and should be handled in a dry environment to prevent degradation. For long-term storage, consider storing under an inert atmosphere.
