2-[(4-Chloro-2-nitrophenyl)amino]ethanol

HC Yellow No 12 (CAS 59320-13-7) reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH supports precise LC-MS/MS and GC-MS quantification across cosmetic and pharmaceutical matrices. It is designed for calibration, method validation, and confirmatory analysis with full traceability. It aligns with these needs: azo hair dye reference standard, LC-MS MS calibration solution, GC-MS quantification material, traceability for method validation, confirmatory analysis compound, multi-residue method development, residue control in cosmetics, pharmaceutical metabolism studies, regulated laboratory quality control. Therefore, you achieve robust performance, consistent signals, and accurate recoveries.

Use this reference standard to build calibration curves, verify instrument response, and monitor precision. Prepare matrix-matched standards for LC-MS/MS or GC-MS, then assess linearity, LOD, and LOQ. Next, confirm identity by ion ratios and retention time. Furthermore, track traceability with lot-specific documentation and a clear audit trail from WITEGA Laboratorien Berlin-Adlershof GmbH. This approach ensures reproducible results during routine analysis and method transfer.

Key features help streamline your workflow:

• High-purity reference standard for confident LC-MS/MS and GC-MS quantification
• Reliable calibration, quality control, and recovery studies
• Excellent stability with recommended storage conditions
• Lot-specific documentation and certificate of analysis for traceability
• Optimized for sensitive detection in complex matrices

Typical use cases include:

• Regulated laboratories performing residue control in cosmetics
• Pharmaceutical research conducting metabolism and fate studies
• Contract labs developing multi-residue methods and confirmatory analysis
• Method validation, performance qualification, and cross-site harmonization
• Routine surveillance, troubleshooting, and proficiency testing

Choose this reference standard from WITEGA Laboratorien Berlin-Adlershof GmbH to support traceable quantification, robust calibration, and dependable confirmatory analysis. Consequently, your LC-MS/MS or GC-MS methods remain accurate, defensible, and ready for regulatory scrutiny.
