Mono-2-ethylhexyl phthalate-D₄

Mono-2-ethylhexyl phthalate-D₄

Mono-2-ethylhexyl phthalate-D4 (CAS 1276197-22-8) is a high-purity reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH for LC MS MS and GC MS workflows. This deuterium labeled plasticizer metabolite standard supports calibration solution for LC MS MS and acts as a GC MS confirmatory analysis standard in sensitive methods. It enables precise quantification, low detection limits, and strong comparability across batches.

As a stable isotope labeled analogue of MEHP, this reference standard delivers reliable traceability, robust calibration, and efficient method validation. Use it to build calibration curves, verify linearity, and assess recovery in routine runs. During confirmatory analysis, it helps demonstrate specificity and rule out interferences. Documentation includes lot-specific details to aid audits. The Mono-2-ethylhexyl phthalate-D4 (CAS 1276197-22-8) designation is clearly stated for unambiguous identification.

Key advantages include:

• Optimized for LC MS MS and GC MS quantification with consistent response.
• Traceable documentation and a comprehensive certificate of analysis.
• High chemical purity with well-defined deuterium incorporation.
• Ready for calibration, quality control checks, and revalidation work.
• Compatible with multi residue screening and metabolism studies.

Typical applications:

• Regulated laboratories performing residue monitoring and compliance testing.
• Pharmaceutical research and development programs.
• Environmental and food control labs building multi residue methods.
• Metabolism and transformation studies in complex matrices.
• Confirmatory analysis to verify identification and quantify targets.

Every lot is manufactured and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH under strict quality procedures. Choose this reference standard to strengthen method robustness, ensure traceability, and maintain long-term comparability across instruments and sites.
