Description
Sulfapyridine (CAS 144-83-2) is a high-purity reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. It is suited as an LC-MS/MS reference standard for sulfonamide analysis and as a GC-MS calibration solution for antibiotic residues. Use it to build robust calibration curves, establish traceability, and perform method validation and confirmatory analysis with confidence.
This reference standard supports quantitative workflows in complex matrices. Analysts in regulated laboratories can rely on consistent purity and comprehensive documentation. Furthermore, pharmaceutical research teams use it during metabolism studies to characterize pathways and to verify identity by MS. It also fits multi-residue method development, where selectivity and accuracy matter.
Key analytical benefits include:
- Reliable calibration for LC-MS/MS and GC-MS quantification
- Traceable measurement results supported by lot-specific documents
- Efficient method validation, including accuracy, precision, and linearity
- Confident confirmatory analysis through verified identity and purity
Typical use cases span residue control, pharmaceutical metabolism studies, and multi-residue method development. Laboratories can prepare stock and working solutions in suitable solvents to match instrument requirements. Short equilibration times and stable response help streamline routine sequences, while clear labeling simplifies calibration curve setup.
Each batch from WITEGA Laboratorien Berlin-Adlershof GmbH is supplied with a detailed Certificate of Analysis. The documentation supports audit-ready records and repeatable performance across batches. In summary, Sulfapyridine (CAS 144-83-2) as a reference standard delivers dependable calibration, robust traceability, and clear confirmation in modern MS-based workflows.
