Diisobutyl phthalate-D₄

Di iso butyl phthalate D4 (CAS 358730-88-8) is a deuterated plasticizer reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. This deuterated plasticizer reference standard supports LC-MS/MS and GC-MS workflows for accurate quantitative measurements. It enables robust calibration and delivers the traceability that regulated methods demand, while keeping sample preparation straightforward.

Use this reference standard to build reliable calibration curves, verify method performance, and perform confirmatory analysis with confidence. It fits routine quality control and advanced research alike. Each lot is prepared for consistent response across instruments, which helps you maintain comparability over time and across sites. In addition, the format supports common solvent systems used in multi-residue screening.

• LC-MS/MS and GC-MS quantitative calibration
• Traceability for audits and data integrity
• Method validation, recovery checks, and matrix effects studies
• Confirmatory analysis and system suitability testing

Typical applications include regulated laboratories, pharmaceutical research, residue control in consumer products and food contact materials, metabolism studies, and multi-residue method development. Furthermore, laboratories benefit from streamlined workflows and clear documentation that facilitate routine reviews and regulatory submissions.

• Optimized response for calibration and quantification
• Stable performance for confirmatory analysis
• Supports screening and targeted assays
• Consistent lot-to-lot behavior for long-term studies
