1-Ethyl-D₅-6,8-difluoro-7-(3-methyl-piperazin-1-yl)-4-oxo-1,4-dihydro-quinoline-3-carboxylic acid hydrochloride

Lomefloxacin D5 hydrochloride is a deuterated fluoroquinolone reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. This stable isotope labeled compound supports robust LC-MS/MS quantification and traceable calibration. Laboratories use it to build reliable calibration curves and to confirm analyte identity with confidence. Its controlled isotopic enrichment improves selectivity and reduces matrix effects, which accelerates method development and routine workflows.

This reference standard performs excellently in LC-MS/MS applications and can be adapted to GC-MS workflows with suitable derivatization strategies. Use it for calibration, system suitability testing, method validation, and confirmatory analysis. Comprehensive documentation supports traceability, ensuring consistent results in regulated environments. Because its behavior mirrors the native analyte, you can achieve accurate quantification in complex matrices and across diverse sample types.

• Regulated laboratories conducting residue control and confirmatory analysis
• Pharmaceutical research on absorption, distribution, metabolism, and excretion
• Metabolism studies for pathway elucidation and metabolite profiling
• Multi-residue method development covering antibacterial drug classes
• Routine quality control and ongoing performance verification

With Lomefloxacin D5 hydrochloride, you can prepare calibration solutions, establish limits of detection and quantification, and verify recovery and precision. The reference standard from WITEGA integrates seamlessly into established procedures, from sample preparation to data review and reporting. It supports traceability requirements and enhances confidence in LC-MS/MS results. Store under recommended conditions and follow validated protocols for consistent performance throughout your analytical campaigns.
