Difloxacin-D₃ hydrochloride

1-(4-Fluorophenyl)-6-fluoro-7-(4-methyl-D₃-piperazin-1-yl)-4-oxo-1,4-dihydroquinoline-3-carboxylic acid hydrochloride

Difloxacin-D3 hydrochloride (CAS 1173021-89-0) is a deuterated fluoroquinolone reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. Designed as a fluoroquinolone reference material and LC-MS/MS calibration standard, it enables accurate quantification in complex matrices. With high purity and known isotopic enrichment, it supports robust calibration curves and clear analyte confirmation. Laboratories choose this material to drive reliable results, improve traceability, and speed up method development.

Use this reference standard to strengthen LC-MS/MS or GC-MS workflows from sample preparation through data evaluation. It offers traceability to gravimetric preparation and supports calibration, method validation, and confirmatory analysis across diverse matrices such as serum, tissue, feed, milk, and water. Because the D3 label minimizes matrix interferences, you achieve stable responses and low detection limits.

• Optimized for quantitative analysis in residue control and veterinary drug monitoring.
• Suitable for pharmaceutical research, metabolism studies, and toxicokinetic profiling.
• Reliable performance for multi-residue method development and routine surveillance.
• Delivered with comprehensive documentation and clear labeling to support audits.

Every batch from WITEGA Laboratorien Berlin-Adlershof GmbH undergoes stringent quality checks to ensure purity, identity, and concentration integrity. Documentation includes batch-specific data to back traceability and reproducibility. The material dissolves readily in common LC-MS solvents and remains stable under recommended storage conditions.

• Supports calibration, method validation, and confirmatory analysis in LC-MS/MS and GC-MS.
• Traceability backed by rigorous manufacturing and controlled weighing procedures.
• Consistent response for precise quantification in complex matrices.

Choose Difloxacin-D3 hydrochloride (CAS 1173021-89-0) when you need consistent calibration, robust method validation, and confident confirmatory analysis.
