(1R,2S,5S)-N-[(1S)-1-Cyano-2-[(3S)-2-oxo-3-pyrrolidinyl]ethyl]-3-[(2S)-3,3-dimethyl-1-oxo-2-[(2,2,2-trifluoroacetyl)amino]butyl]-6,6-dimethyl-3-azabicyclo[3.1.0]hexane-2-carboxamide

Nirmatrelvir PF 07321332 (CAS 2628280-40-8) is a high-purity reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. As a SARS-CoV-2 protease inhibitor standard, it supports LC-MS/MS and GC-MS workflows from calibration to confirmatory analysis. Use it to establish reliable quantification and to maintain traceability across studies and instruments.

This reference standard enables confident calibration and robust method validation. Build linear calibration curves, verify accuracy and precision, and confirm identities in complex matrices. Additionally, prepare matrix-matched calibrators or spike recoveries for consistent response and improved comparability. Moreover, the material supports routine quality control and stability checks.

• Instrumental use: LC-MS/MS and GC-MS quantification, confirmation, and troubleshooting.
• Validation tasks: linearity, accuracy, precision, LOD and LOQ assessment, and recovery studies.
• Traceability: documented preparation supports reproducibility and audit-ready records.

Typical applications include:

• Regulated laboratories and quality control units
• Pharmaceutical research and antiviral development
• Residue control and compliance testing
• Metabolism studies and biotransformation research
• Multi-residue method development in complex matrices

With Nirmatrelvir PF 07321332 (CAS 2628280-40-8), analysts can compare results across instruments and sites. Furthermore, the stable composition favors accurate calibration at relevant concentration ranges. Therefore, you can streamline workflows from screening to confirmation with fewer repeats and clearer decisions.

This product is available directly from WITEGA Laboratorien Berlin-Adlershof GmbH. Choose this reference standard to strengthen traceability, improve method robustness, and support reliable LC-MS/MS or GC-MS data throughout your project lifecycle.
