4-Hydroxy-3-(ethoxy-D₅)benzaldehyde

Ethyl D5 Vanillin (CAS 1335401-74-5) reference standard enables precise LC-MS/MS and GC-MS quantification. This stable isotope labeled aldehyde standard supports calibration, traceability, and confirmatory analysis. Produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH, it delivers reliable results from the first run.

Use it to build linear calibrations with excellent accuracy. Short runs benefit from clear separation and robust ion ratios. You can validate methods, verify recoveries, and secure measurement uncertainty. The defined mass shift simplifies identification in complex matrices.

• Optimized for LC-MS/MS and GC-MS quantification and screening.
• Traceable purity with comprehensive documentation and CoA.
• Consistent response for calibration and quality control.
• Stable isotopic labeling for selective confirmation.

Typical applications include:

• Regulated laboratories performing official residue control.
• Pharmaceutical research and metabolism studies.
• Multi-residue method development in food or environmental testing.
• Routine confirmation of target analytes in complex samples.

The reference standard is supplied in convenient concentration or neat form upon request. It dissolves well in common LC or GC solvents. Storage guidelines maintain integrity over its shelf life. Technical support from WITEGA Laboratorien Berlin-Adlershof GmbH helps with spiking levels, calibration ranges, and matrix setup.

Choose Ethyl D5 Vanillin (CAS 1335401-74-5) to strengthen traceability and reproducibility across your workflow. It fits validation, daily calibration, and independent confirmatory analysis.
