Mephenytoin-D₈

(±)-5-Ethyl-3-methyl-D₃-5-phenyl-D₅-imidazolidine-2,4-dione

Mephenytoin-D8 is a high-purity reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. Laboratories deploy this deuterated reference standard across LC-MS/MS and GC-MS workflows. As an LC-MS/MS calibration standard and metabolism study reference material, it enables traceable quantification and supports robust method validation and confirmatory analysis.

This reference standard helps analysts calibrate instruments, verify linearity, and assess recovery. It provides reliable response factors for deuterium-labeled analyte tracking. Therefore, you gain confidence in identification and quantification, even in complex matrices.

Typical applications include:

• Regulated laboratories performing routine residue monitoring and confirmatory analysis
• Pharmaceutical research studying biotransformation and pharmacokinetics
• Residue control in food, feed, and environmental samples
• Metabolism studies and biomarker investigations
• Multi-residue method development and performance verification

Use this material to support calibration curves, matrix-matched validation, and long-term trend monitoring. It helps demonstrate trueness, precision, and limits of quantification under real sample conditions. In addition, the product facilitates traceability by linking instrument response to a well-characterized reference standard.

Key advantages:

• Optimized for LC-MS/MS and GC-MS quantification with stable isotopic labeling
• Supports calibration, method validation, and confirmatory analysis
• Improves selectivity in complex matrices and challenging workflows
• Suitable for single-analyte and multi-residue screening strategies

Each batch of the Mephenytoin-D8 reference standard is produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. Choose it to enhance traceability, streamline quality control, and strengthen confidence in analytical decisions from development to routine testing.
