Dimethyl phthalate-D₄

Dimethyl phthalate-D₄

Dimethyl phthalate-D4 (CAS 93951-89-4) is a deuterated reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. It supports precise LC-MS/MS and GC-MS workflows, from calibration and traceability to method validation and confirmatory analysis. As a reliable reference standard, it helps laboratories build robust calibration curves, verify retention time, and maintain compliance with stringent quality requirements.

This isotope-labeled material mirrors the native analyte during extraction, separation, and ionization. Therefore, it reduces matrix effects and improves quantitative accuracy. Use it to establish linear ranges, determine LOD and LOQ, and cross-check system suitability across platforms. Additionally, Dimethyl phthalate-D4 (CAS 93951-89-4) strengthens data defensibility in confirmatory workflows.

• LC-MS/MS and GC-MS quantification with consistent response
• Traceable calibration and response factor verification
• Method validation covering accuracy, precision, selectivity, and recovery
• Confirmatory analysis aligned with regulatory criteria

Typical use cases include:

• Regulated laboratories performing routine residue control
• Pharmaceutical research focused on impurity and contaminant studies
• Metabolism studies and kinetic profiling in diverse matrices
• Multi-residue method development and optimization

Manufactured under rigorous quality processes at WITEGA Laboratorien Berlin-Adlershof GmbH, this reference standard is delivered with comprehensive documentation to support traceability and audit readiness. Moreover, the D4 labeling ensures closely matched chromatographic behavior to the native analyte, enabling reliable calibration and recovery assessment without compromising selectivity. Consequently, Dimethyl phthalate-D4 (CAS 93951-89-4) provides consistent quantification across instruments and matrices.

Deploy this reference standard to prepare stock and working solutions, verify linearity, and set acceptance criteria for daily performance checks. Furthermore, it facilitates cross-platform comparability between LC-MS/MS and GC-MS workflows, helping laboratories maintain accuracy from method development through routine confirmatory analysis.
