4-Amino-6-trichloroethenyl-1,3-benzene-¹³C₆-disulfonamide

Clorsulon 13C6 (CAS 1325559-24-7) is a high-purity reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. It is designed for LC-MS/MS and GC-MS analytical quantification, traceability, calibration, method validation, and confirmatory analysis. Moreover, this stable isotope labeled reference standard supports LC-MS/MS calibration solution preparation, enables GC-MS confirmatory analysis, and fits seamlessly as method validation materials in routine and research workflows.

Engineered as an isotopically labeled analogue of the target analyte, the material delivers precise mass differentiation, robust selectivity, and improved accuracy. Therefore, it helps laboratories construct reliable calibration curves, verify linearity, and maintain traceability across batches. Additionally, its consistent performance supports matrix-matched calibration, reduces variability, and strengthens identification criteria for confirmatory analysis in complex samples.

Key benefits of this reference standard include:

• High chemical purity and identity verification to support confident LC-MS/MS and GC-MS results.
• Lot-specific documentation and traceability for defensible data and audits.
• Consistent response characteristics that facilitate accurate calibration and recovery checks.
• Uniform carbon-13 labeling for clear mass offset and enhanced selectivity in complex matrices.

Typical applications span multiple sectors:

• Regulated laboratories needing reliable calibration and confirmatory analysis.
• Pharmaceutical research focusing on precision quantification and metabolism pathway studies.
• Residue control programs in food and environmental monitoring.
• Metabolism studies requiring definitive identification and quantification.
• Multi-residue method development where robustness and traceability are critical.

Choose Clorsulon 13C6 (CAS 1325559-24-7) from WITEGA Laboratorien Berlin-Adlershof GmbH to streamline calibration, strengthen method validation, and secure traceable, reproducible LC-MS/MS or GC-MS measurements. Consequently, your laboratory can confidently meet performance criteria, simplify routine quality control, and produce defensible results.
