Laboratories use this material for LC-MS/MS and GC-MS quantification, traceable calibration, method validation, and confirmatory analysis. It delivers consistent responses and reliable retention, even in complex matrices. Keywords: deuterated sulfonamide standard, LC-MS/MS calibration solution, GC-MS confirmation material, traceable analytical reference material, veterinary antibiotic residue testing, isotope-labeled antibacterial compound, multi-residue method development, matrix-matched calibration, quantitative mass spectrometry, pharmaceutical metabolism studies.

This reference standard offers excellent purity and lot-to-lot consistency. Each batch includes documentation to support traceability and measurement reliability. As a stable isotope-labeled analog, it mirrors the native analyte and improves correction for matrix effects. Consequently, calibration curves remain robust and linear across relevant ranges. The material supports both screening and targeted quantification. It is prepared and supplied by WITEGA Laboratorien Berlin-Adlershof GmbH with strict quality oversight.

Typical applications include:

• Regulated laboratories requiring traceable calibration and proficiency testing materials.
• Pharmaceutical research focusing on bioanalytical quantification and assay transfer.
• Residue control programs monitoring veterinary drugs in food and feed.
• Metabolism studies assessing transformation products and kinetic profiles.
• Multi-residue method development across LC-MS/MS and GC-MS workflows.

Analytical advantages of this reference standard:

• Traceability: supports defensible reporting and audit-ready documentation.
• Calibration and linearity: enables accurate curves and stable response factors.
• Validation: suitable for recovery, precision, and accuracy experiments.
• Confirmatory analysis: facilitates specific MRM transitions and ion ratio checks.
• Compatibility: optimized for LC-MS/MS; viable in GC-MS with appropriate derivatization.
