Description

Sulfachloropyrazine-13C6 is a stable isotope-labeled analog of the veterinary antibacterial agent sulfachloropyrazine. This compound is essential as an internal standard in quantitative mass spectrometry, ensuring the highest accuracy and reliability in analytical methods. It is primarily required by research laboratories, pharmaceutical companies, and contract research organizations (CROs) engaged in veterinary drug residue analysis, pharmacokinetic studies, and method development.

Application

• Internal Standard for LC-MS/MS: Critical for the precise quantification of sulfachloropyrazine and related sulfonamides in complex biological matrices like plasma, tissue, and milk.
• Veterinary Drug Residue Testing: Supports compliance testing in food safety programs to monitor for sulfonamide residues in animal-derived products.
• Metabolite Identification & Pharmacokinetics: Used in ADME (Absorption, Distribution, Metabolism, Excretion) studies to track the parent drug and its metabolites.
• Method Development & Validation: Serves as a key reference material for developing and validating robust, regulatory-compliant analytical methods (e.g., following FDA or EU guidelines).
• Quality Control in Reference Material Production: Employed in the calibration and quality assurance of certified reference materials (CRMs).
• Environmental Fate Studies: Aids in tracing the environmental dispersion and degradation of sulfachloropyrazine in ecological studies.

Quality Control

Our Sulfachloropyrazine-13C6 is manufactured under strict quality systems to ensure isotopic and chemical purity for demanding analytical applications. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing isotopic enrichment (Atom % 13C), chemical purity by HPLC, and identity confirmation by NMR and MS. We adhere to relevant standards for high-purity reference materials to support GLP and ISO 17025 accredited laboratories.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C. This product is hygroscopic (moisture-sensitive) and should be handled under anhydrous conditions to maintain stability. Allow the sealed vial to equilibrate to room temperature before opening to prevent moisture condensation.
