Sulfalene-¹³C₆ Sulfamethoxypyrazine-¹³C₆

4-Amino-N-(3-methoxypyrazin-2-yl) benzene-¹³C₆-sulfonamide

Sulfalene-13C6 Sulfamethoxypyrazine-13C6 is a stable isotope labeled reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. It enables precise LC-MS/MS and GC-MS quantification, supports calibration and traceability, and streamlines method validation and confirmatory analysis. Therefore, it fits seamlessly into regulated workflows and multi-matrix applications.

You can apply this reference standard throughout the full analytical lifecycle. Build linear calibration curves, verify selectivity, and confirm identities with matched ion transitions. Moreover, use it to assess matrix effects, recovery, and ruggedness. Its stable isotope labeling improves accuracy in complex samples and helps control variability.

• LC-MS/MS calibration and response factor determination
• GC-MS screening and confirmation of residues
• Method validation for accuracy, precision, linearity, and selectivity
• Traceability for routine quality control and system suitability
• Metabolism and biotransformation studies
• Multi-residue method development across diverse matrices

Analytical teams in regulated laboratories, pharmaceutical research, residue control, and academic settings benefit from consistent results. Additionally, clear documentation supports audit readiness and data integrity. Use this material to strengthen calibration hierarchies and to verify quantitative performance at decision limits.

For best practice, prepare calibration standards and quality control samples according to your SOPs and the product documentation. Then, evaluate recovery and matrix effects using spike-recovery experiments. Finally, apply Sulfalene-13C6 Sulfamethoxypyrazine-13C6 during confirmatory analysis to corroborate target findings with robust isotope-based criteria.
