Florfenicol-D3Florfenicol D3

2,2-Dichloro-N-[(1S,2R)-1-fluoromethyl-2-hydroxy-2-[(4-methyl-D3-sulfonyl)phenyl]ethyl]acetamide

The Florfenicol-D3 reference standard (CAS Reg. No. 2213400-85-0) is designed for precise quantitative analysis in regulated laboratories. It supports advanced isotope-labelled antibiotics residue testing and veterinary drug monitoring via LC-MS/MS laboratory workflows. This product is a reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH and ensures consistent analytical performance.

Florfenicol-D3 is a deuterated analogue of florfenicol and plays an important role in modern residue analysis. Laboratories require highly characterized reference standards to achieve reliable quantification in complex matrices such as meat, milk, and feed. Therefore, this material provides defined identity and purity for demanding applications. In addition, it supports harmonized measurement procedures across different analytical platforms.

In LC-MS/MS workflows, the Florfenicol-D3 reference standard enables accurate calibration and sensitive detection. Analysts use it to establish calibration curves, evaluate instrument response, and verify system suitability. Moreover, it assists during method validation by allowing assessment of precision, recovery, and linearity. As a result, confirmatory analysis meets regulatory expectations and audit requirements.

GC-MS methods also benefit from this reference standard during targeted screening and verification procedures. Because traceability is essential in regulated environments, laboratories integrate this product into their quality management systems. Consequently, analytical data remain reproducible and comparable over time.

Typical applications include:

• Veterinary drug residue control in food producing animals
• Calibration and quantitative analysis via LC-MS/MS
• Method development and multi-residue method validation
• Pharmaceutical research and metabolism studies

Each Florfenicol-D3 reference standard from WITEGA Laboratorien Berlin-Adlershof GmbH is manufactured under controlled conditions. Therefore, laboratories benefit from reliable calibration, documented traceability, and robust analytical results in routine and research settings.
