7-(6R,7R)[[(2R)-2-Amino-2-phenylacetyl]amino]-3-methyl-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylic acid

Cefalexin Cephalexin (CAS 15686-71-2) is a pharmaceutical reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. This beta-lactam antibiotic reference standard supports LC-MS/MS and GC-MS quantification in complex matrices. It enables traceable calibration and strong method validation for residue control and research workflows. Consequently, you gain confidence in confirmatory analysis and routine quality control.

Prepared from high-purity material and verified by orthogonal techniques, the reference standard delivers lot-to-lot reliability. Use it to establish linearity, check accuracy and precision, and verify detection limits. Additionally, it assists in matrix-matched calibration across food, environmental, and pharmaceutical samples.

Key advantages:

• Traceable certificate of analysis for each lot.
• Optimized for LC-MS/MS and GC-MS workflows.
• Defined purity for quantitative calibration.
• Clear solubility and storage guidance for stable handling.
• Suitable for confirmatory analysis and proficiency testing.

Typical applications include:

• Regulated laboratories performing compliance testing.
• Pharmaceutical research and development studies.
• Residue control and surveillance programs.
• Metabolism studies and metabolite profiling.
• Multi-residue method development and validation.

When integrating Cefalexin Cephalexin (CAS 15686-71-2) into your workflow, you streamline calibration and reduce uncertainty. Prepare gravimetric stock solutions, then perform serial dilutions with suitable solvents. Finally, document instrument response factors to maintain traceability and reproducibility across batches and instruments.
