Fluorescent brightener 184

2,5-Bis(5-tert-butyl-2-benzoxazolyl)thiophene

Fluorescent brightener 184 (CAS 7128-64-5) reference standard from WITEGA Laboratorien Berlin-Adlershof GmbH enables confident LC-MS/MS calibration and serves as a traceable analytical standard. It supports robust workflows from screening to confirmation. Therefore, laboratories get reproducible data and clear decision points.

This high-purity material underpins LC-MS/MS and GC-MS quantification. Use it for calibration curve preparation, instrument qualification, and daily system checks. It also strengthens method validation, including accuracy, precision, linearity, and LOQ verification. Furthermore, it secures traceability across batches and instruments for audits.

• Verified identity and purity for reliable calibration.
• Defined documentation to support full traceability.
• Optimized handling for rapid solution preparation.
• Intended for confirmatory analysis under regulated conditions.

Typical applications include:

• Regulated laboratories conducting routine residue control.
• Pharmaceutical research exploring formulation and extractables.
• Metabolism studies and transformation product assessment.
• Multi-residue method development across complex matrices.

Prepare stock solutions with suitable solvents based on method needs. Then create matrix-matched calibration to minimize ion suppression. Document lot numbers for complete audit trails. Finally, continue system suitability checks to maintain performance.

This reference standard is produced and distributed exclusively by WITEGA Laboratorien Berlin-Adlershof GmbH. It arrives with a Certificate of Analysis for traceable documentation. Consequently, you integrate it seamlessly into existing LC-MS/MS or GC-MS workflows. Use Fluorescent brightener 184 (CAS 7128-64-5) to standardize quantitative methods and improve comparability across sites.
