(2S,5R,6R)-3,3-Dimethyl-6-[(5-methyl-3-phenyl-13C6-1,2-oxazol-4-yl)amido]-7-oxo-4-thia-1-azabicyclo[3.2.0]hep-tane-2-carboxylic acid sodium salt

Oxacillin 13C6 sodium salt is a stable isotope-labeled reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. It is purpose-built for LC-MS/MS and GC-MS workflows and supports analytical quantification, traceability, calibration, method validation, and confirmatory analysis. As a beta lactam antibiotic reference standard and a traceable analytical standard suitable for an LC-MS/MS calibration solution, it enables consistent performance in regulated environments and multi-residue method development.

The 13C6 isotopic label closely mirrors the native compound. Therefore, Oxacillin 13C6 sodium salt aligns retention behavior and ionization characteristics with the target analyte. This similarity improves calibration accuracy and helps reduce matrix effects during quantitative analysis. Furthermore, batch-to-batch consistency from WITEGA supports reliable long-term monitoring programs.

Typical applications include:

• Regulated laboratories that require traceable quantification and robust confirmatory analysis
• Pharmaceutical research for pharmacokinetic studies and quality control
• Residue control programs monitoring beta-lactam antibiotics in complex matrices
• Metabolism studies assessing transformation products with LC-MS/MS or GC-MS
• Multi-residue method development across diverse sample types

Designed for flexibility, this reference standard integrates smoothly into existing methods. It supports calibration curve preparation, recovery assessments, and routine system suitability checks. Moreover, the material strengthens method validation by improving precision, linearity, and limits of quantification.

Every lot of Oxacillin 13C6 sodium salt from WITEGA Laboratorien Berlin-Adlershof GmbH is provided with comprehensive documentation to aid traceability. As a result, laboratories can implement defensible analytical workflows and meet stringent data quality objectives.

Key benefits:

• Optimized for LC-MS/MS and GC-MS quantification and confirmatory analysis
• Stable isotope labeling for accurate calibration and robust traceability
• Suited to method validation, from linearity to precision and recovery
• Trusted production and distribution by WITEGA Laboratorien Berlin-Adlershof GmbH
