(αS)-6-Methoxy-α-methyl-2-naphthaleneacetic acid

Naproxen (CAS 22204-53-1) reference standard is produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. This chiral arylpropionic acid reference supports precise LC-MS/MS and GC-MS workflows. It enables traceable calibration, reliable quantification, and confident confirmatory analysis from the first injection. You can integrate it quickly in routine or research methods without reworking validated procedures.

Each batch of this reference standard is manufactured with stringent controls by WITEGA Laboratorien Berlin-Adlershof GmbH. Consistent purity and identity help you build robust calibration curves and meet documentation requirements. In LC-MS/MS or GC-MS, the material provides accurate response factors, enhances linearity, and improves day-to-day reproducibility. It also streamlines method validation steps, including selectivity, recovery, matrix effects, and stability assessments.

Typical applications include:

• Regulated laboratory workflows needing traceable calibration and system suitability
• Pharmaceutical research focused on dose formulation and quality control
• Residue control programs and environmental monitoring
• Metabolism and pharmacokinetic studies requiring enantiomer-specific quantification
• Multi-residue method development in complex matrices

This Naproxen (CAS 22204-53-1) reference standard fits quantitative assays across a broad concentration range. It supports confirmatory analysis for screening positives and strengthens measurement uncertainty budgets. Moreover, it aligns with routine QA/QC practices, providing dependable lot-to-lot performance.

For best results, prepare calibration solutions gravimetrically and document all dilutions. Use appropriate solvents compatible with your chromatographic system. Additionally, verify retention time, fragmentation patterns, and relative response during sequence setup. With the Naproxen (CAS 22204-53-1) reference standard from WITEGA Laboratorien Berlin-Adlershof GmbH, you can advance method validation, improve traceability, and deliver reproducible data across LC-MS/MS and GC-MS platforms.
