Sulfatroxazole-D₄

4-Amino-N-(4,5-dimethyl-3-isoxazolyl)benzene-D₄-sulfonamide

Introducing Sulfatroxazole-D4, a high-purity reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. This stable isotope labeled reference material supports LC-MS/MS calibration standard workflows and GC-MS confirmation standard applications, delivering a traceable analytical reference for your method validation compound and multi-residue method development standard.

Use this reference standard to establish robust calibration curves and achieve accurate quantification in complex matrices. It provides reliable traceability for routine testing and confirmatory analysis. Moreover, it integrates seamlessly with LC-MS/MS or GC-MS methods, helping you verify identity through ion ratios and retention time.

Key advantages include:

• High chemical purity for precise response factors
• Documented traceability and batch-to-batch consistency
• Optimized for LC-MS/MS and GC-MS response stability
• Supports calibration, method validation, and quality control
• Delivered with product documentation for compliant workflows

Typical applications:

• Regulated laboratories performing residue control and confirmatory testing
• Pharmaceutical research and metabolism studies
• Development of multi-residue methods across varied matrices
• Calibration verification and routine system suitability checks

Prepare gravimetric stock solutions to minimize uncertainty. Then create matrix-matched standards to control matrix effects and improve accuracy. Additionally, use replicate levels to establish linearity and detection limits. The reference standard helps confirm analyte identity and ensures data integrity in targeted methods.

Backed by the expertise of WITEGA Laboratorien Berlin-Adlershof GmbH, Sulfatroxazole-D4 supports traceable calibration and reliable quantification. Therefore, it is a strong choice for laboratories seeking confident LC-MS/MS and GC-MS performance.
