Cefacetrile-¹³C3

(6R,7R)-3-(Acetoxymethyl)-7-(cyanoacetamido-¹³C₃)-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylic acid

Cefacetrile-13C3 is a stable isotope labeled reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. It supports LC-MS/MS and GC-MS quantification with robust accuracy. Use it as an LC-MS/MS calibration solution and a traceable analytical standard. The material helps correct matrix effects and improves reproducibility. Laboratories choose it for sensitive beta-lactam analysis and clear identification.

This reference standard streamlines calibration, traceability, method validation, and confirmatory analysis. It enables linear response across working ranges. Prepare single-compound or mixed working solutions with confidence. Because the isotopic label is integrated, mass transitions remain specific. Therefore, interferences are minimized and carryover is easy to monitor.

• High purity and identity confirmed for reliable quantification
• Optimized for LC-MS/MS and GC-MS workflows
• Supports calibration, traceability, and quality control
• Designed for method validation and confirmatory analysis
• Suitable for multi-residue screening and targeted assays

Typical use cases include regulated laboratories, pharmaceutical research, residue control, metabolism studies, and multi-residue method development. Analysts apply the Cefacetrile-13C3 reference standard for spike recovery experiments, matrix-matched calibration, and daily system suitability. It also supports proficiency testing and retrospective data review.

• Regulated testing and residue control programs
• Pharmaceutical development and metabolic pathway studies
• Food, feed, and environmental matrices
• Long-term QC trending and system checks

The Cefacetrile-13C3 reference standard ships with clear labeling and batch information. Dissolve in common LC solvents such as methanol or acetonitrile. Store according to validated procedures to maintain integrity. Moreover, pair it with appropriate system controls to document traceability. Backed by WITEGA expertise, it fits seamlessly into routine and research workflows.
