threo-Chloramphenicol; 100 μg/ml in acetonitrile ISO 17034

2,2-Dichloro-N-[(1RS,2RS)-2-hydroxy-1-hydroxymethyl-2-(4-nitrophenyl)-ethyl] acetamide (mixture of enantiomers)

<em>threo</em>-Chloramphenicol; 100 μg/ml in acetonitrile ISO 17034 (CAS 2787-09-9) is a ready-to-use Certified Reference Material produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. As a certified antibiotic CRM and an LC-MS/MS calibration solution, it delivers consistent performance with metrological traceability for routine and advanced workflows. The ISO 17034 framework ensures competence for production, homogeneity, and assigned values, so you can trust your calibration and confirmatory results.

This solution supports robust quantitative analysis by LC-MS/MS and GC-MS. It enables accurate calibration curves, traceable measurements, and clear quality documentation. The <em>threo</em> form represents the racemic mixture of the active enantiomers, making it suitable for a broad range of matrices and study designs.

• Ready-to-use concentration: 100 µg/mL in acetonitrile for minimal preparation time.
• Designed for LC-MS/MS and GC-MS quantification with excellent response behavior.
• Supports traceability, calibration, method validation, and confirmatory analysis.
• Mixture of enantiomers (<em>threo</em>) for realistic assay development and verification.
• Manufactured under ISO 17034 with lot-specific documentation.

Typical applications include regulated environments and research settings where confidence is essential.

• Regulated laboratories requiring documented traceability and clear uncertainty budgets.
