Bis(4-hydroxyphenyl-¹³C₆)sulfone

Bisphenol S 13C12 (CAS 1991267-29-8) is a stable isotope labeled reference standard for precise LC-MS/MS and GC-MS quantification. Produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH, it supports traceable calibration and robust confirmatory analysis in demanding workflows. Keywords: stable isotope labeled reference standard, phenolic contaminant analysis, urine biomonitoring by LC-MS/MS, environmental water screening GC-MS, traceable calibration solution, confirmatory analysis in regulated labs, multi-residue method development, pharmaceutical metabolism studies, residue control in food packaging, calibration and QC for endocrine disruptors.

Use this reference standard to build linear calibration curves, evaluate matrix effects, and verify recoveries with confidence. It streamlines method validation and supports traceability from sample preparation through data review. Analysts can confidently apply it in LC-MS/MS and GC-MS to quantify trace levels in complex matrices while maintaining consistency across instruments and batches.

• High chemical purity and identity confirmation by orthogonal techniques.
• Gravimetrically assigned concentration for reliable calibration.
• Suitable solvent for direct dilution into typical mobile phases.
• Stability guidance and recommended storage conditions.
• Lot-specific documentation to support audits and quality assurance.

Typical users include regulated laboratories, environmental monitoring centers, and research groups focused on endocrine disruptor exposure. It also supports pharmaceutical research, metabolism studies, residue control programs, and multi-residue method development. The Bisphenol S 13C12 (CAS 1991267-29-8) reference standard helps you meet method performance criteria, confirm target identity, and document traceability for defensible results.

• Regulated laboratories verifying compliance limits.
• Pharmaceutical research exploring biotransformation pathways.
• Residue control in food packaging and consumer product testing.
• Environmental screening of water, soil, and wastewater.
• Confirmatory analysis to strengthen accreditation evidence.

Integrate this reference standard into LC-MS/MS or GC-MS methods to enhance calibration accuracy, reduce uncertainty, and improve decision-making. For availability, packaging formats, or custom concentrations, contact WITEGA Laboratorien Berlin-Adlershof GmbH.
