EDTA disodium salt dihydrate

N,N’-1,2-Ethanediylbis-N-(carboxymethyl)glycine disodium salt dihydrate

EDTA disodium salt dihydrate (CAS 6381-92-6) is a high-purity reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. Laboratories choose this chelating agent reference standard for LC-MS/MS and GC-MS analytical quantification, traceability, calibration, method validation, and confirmatory analysis. Start your workflow with reliable calibration curves and stable performance.

This material supports accurate identification and precise determination across diverse matrices. Prepare stock and working solutions with confidence. The stable dihydrate form promotes consistent response and recovery. Furthermore, it integrates smoothly into existing procedures and audit-ready documentation.

• High purity and verified identity for accurate calibration
• Traceable documentation that supports defensible data
• Compatible with LC-MS/MS and GC-MS workflows
• Useful for single and multi-residue method development
• Suited for confirmatory analysis and routine quality control

Use this reference standard to build linear calibration ranges, optimize ionization, and verify instrument performance. It helps assess precision, accuracy, and limits of detection during method validation. Moreover, it supports long-term traceability so you can compare results across batches and instruments.

• Regulated laboratories that require defensible quantification
• Pharmaceutical research and quality control programs
• Residue control in food, feed, and environmental samples
• Metabolism studies and pathway elucidation
• Multi-residue method development and ruggedness testing

Practical guidance: prepare calibration standards in appropriate solvent or matrix, bracket the expected range, and verify each level through replicate injections. Then confirm target identity using qualifier ions or transitions. Finally, document all steps to maintain traceability.
