[5-(Hydroxyphenylmethyl)-1H-benzimidazol-2-yl] carbamic acid methyl-D₃ ester

5 Hydroxymebendazole D3 (CAS 1173020-86-4) is a deuterated benzimidazole metabolite standard and a high-purity reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. It supports confident identification and accurate measurement in LC-MS/MS and GC-MS workflows. With reliable documentation and batch traceability, it integrates smoothly into regulated environments.

Use this reference standard for quantification, calibration curve preparation, method validation, and confirmatory analysis. Because it is deuterium labeled, it closely follows the native analyte during sample preparation and ionization. Therefore, you can evaluate recovery and matrix effects with clarity. Furthermore, consistent response helps tighten precision across sequences.

Typical application areas include regulated laboratories, pharmaceutical research, residue control, metabolism studies, and multi-residue method development. The material fits routine QC and new method setup alike. Moreover, it enables traceable reporting that auditors can verify.

• High chemical purity and defined identity for robust selectivity
• Gravimetrically prepared lots and documentation to support traceability
• Optimized for LC-MS/MS and GC-MS quantification and confirmation
• Reliable for calibration, validation, and long-term monitoring
• Produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH

For best results, establish linear or weighted calibration with several levels. Then confirm retention time and qualifier ratios. Next, verify recoveries in matrix. Finally, document lot numbers and preparation records for full traceability. Use 5 Hydroxymebendazole D3 (CAS 1173020-86-4) to strengthen confidence in residues, metabolites, and pharmaceutical matrices. When you need dependable performance, choose a reference standard from WITEGA Laboratorien Berlin-Adlershof GmbH.
