4-(Acetylamino)-2-ethoxybenzoic acid methyl ester

Ethopabate (CAS 59-06-3) is a high-purity coccidiostat reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. It supports LC-MS/MS calibration and GC-MS quantification in residue and research workflows. Analysts use it for traceable calibration, method validation, and confirmatory analysis. As a result, laboratories gain confidence in identification, quantification, and reporting.

Choose this material to achieve robust quantification across instruments and matrices. Each lot includes documentation that supports traceability and consistency. The reference standard helps verify linearity, recovery, and measurement uncertainty. Consequently, results remain reliable and comparable across batches, sites, and projects.

• Regulated laboratories performing residue control and routine quality control.
• Pharmaceutical research investigating metabolism and biotransformation pathways.
• Food and feed testing using multi-residue method development.
• Academic studies requiring reproducible calibration and confirmation.

This reference standard is optimized for modern MS workflows. It integrates easily into validated methods and SOPs. Use it to build calibration curves, set reporting limits, and confirm target identity with orthogonal criteria. Furthermore, it streamlines documentation for audits and accreditation.

• Ready for LC-MS/MS and GC-MS workflows.
• Facilitates calibration curves, system suitability, and retention time checks.
• Supports spiking experiments and matrix-matched calibration.
• Enables confirmatory analysis with precise mass transitions.

Moreover, WITEGA Laboratorien Berlin-Adlershof GmbH ensures consistent production and reliable distribution. Ethopabate (CAS 59-06-3) integrates smoothly into routine QA plans and method transfers. Use this reference standard to strengthen traceability, enhance comparability, and improve confidence in every result.
