1-[[(6R,7R)-7-[[(2Z)-(2-amino-4-thiazolyl)(methoxyimino)acetyl]amino]-2-carboxy-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-en-3-yl]methyl]-5,6,7,8-tetrahydroquinolinium sulfate

Cefquinome sulfate (CAS 118443-89-3) reference standard is produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. It supports LC-MS/MS and GC-MS analytical quantification, traceable calibration, method validation, and confirmatory analysis. As a beta-lactam antibiotic reference standard, it enables veterinary antimicrobial residue analysis with confidence. Therefore, regulated laboratories can achieve consistent, defensible results.

Use this high-quality reference standard to build robust calibration curves and to verify recovery, precision, and linearity. Moreover, it helps establish traceability from stock solution to final measurement. Analysts can streamline multi-residue workflows and reduce rework. In addition, it fits routine QC checks and system suitability tests.

• Quantitative calibration for LC-MS/MS and GC-MS methods
• Confirmatory analysis to meet regulatory acceptance criteria
• Method validation, including linearity, LOQ, accuracy, and matrix effects
• Quality control for day-to-day performance monitoring
• Support for metabolism studies and development of multi-residue screens

Pharmaceutical research teams and residue control laboratories rely on this reference standard for screening and targeted quantification. Furthermore, calibration with Cefquinome sulfate (CAS 118443-89-3) improves comparability across instruments and sites. The material is suitable for spike-and-recovery experiments, matrix-matched calibration, and control sample preparation.

Prepare working solutions in appropriate solvents for your method, and document each step to maintain traceability. Then verify calibration and confirm identity using retention time and ion ratios. With Cefquinome sulfate (CAS 118443-89-3) as your reference standard, you strengthen data integrity across validation and routine batches.
