DTPD

N,N’-Di-p-tolyl-p-phenylenediamine

DTPD (CAS 620-91-7) reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH supports accurate LC-MS/MS and GC-MS quantification. It enables calibration, traceability, method validation, and confirmatory analysis in demanding workflows. Key uses include: reference standard for LC-MS/MS, GC-MS calibration solution, method validation material, traceability for quantification, confirmatory analysis control, pharmaceutical research quality control, residue analysis reference, metabolism study tool, multi-residue method development.

This material helps laboratories build linear calibration ranges, verify selectivity, and check recovery. It suits screening and targeted quantification. Moreover, clear batch documentation simplifies audits and supports traceable reporting.

• High purity and identity confirmation for reliable quantification
• Lot-specific certificate of analysis with concentration data
• Guidance on solvents, storage, and stability
• Broad compatibility with LC-MS/MS and GC-MS systems
• Traceable preparation for calibration curves and QC samples

Use this reference standard in regulated laboratories, pharmaceutical research, residue control programs, metabolism studies, and multi-residue method development. Analysts can prepare stock solutions, dilute to working levels, and spike matrices to evaluate precision and accuracy. Consequently, method validation progresses faster and with fewer re-runs.

The DTPD (CAS 620-91-7) reference standard from WITEGA integrates smoothly into SOPs. It supports confirmatory analysis, ongoing quality control, and instrument performance tracking. In addition, responsive support and consistent batch availability from WITEGA Laboratorien Berlin-Adlershof GmbH help maintain continuity across projects and ensure dependable results.
