DNSHA

3,5-Dinitrosalicylic acid 2-(carboxymethylene)hydrazide

DNSHA (CAS 1089167-64-5) reference standard supports precise LC-MS/MS calibration and GC-MS quantification for reliable results. This traceable analytical standard helps laboratories meet accuracy goals and streamline method validation. Consequently, you can build robust calibration curves and achieve confident confirmatory analysis.

Produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH, this reference standard arrives with batch-specific documentation. You receive a detailed Certificate of Analysis including purity, identity, and uncertainty data. Therefore, traceability is clear and audit-ready. Controlled manufacturing and rigorous testing ensure consistent performance across lots.

Use this reference standard throughout your workflow:

• Analytical quantification by LC-MS/MS or GC-MS with robust calibration curves.
• Traceable calibration and system suitability checks.
• Method validation, including accuracy, precision, and linearity assessments.
• Confirmatory analysis for targeted and screening assays.

Typical application areas include:

• Regulated laboratories requiring documented traceability and reliable results.
• Pharmaceutical research and development workflows.
• Residue control in food, feed, and environmental monitoring.
• Metabolism studies and structural elucidation projects.
• Multi-residue method development with stringent performance criteria.

Additionally, the packaging and documentation are designed for seamless integration into QA systems. Clear labeling and lot traceability simplify inventory and audit processes. With DNSHA (CAS 1089167-64-5) reference standard from WITEGA Laboratorien Berlin-Adlershof GmbH, you can calibrate confidently, validate efficiently, and confirm results with certainty.
