Description

Cyclohexane-1,2-Dicarboxylic Acid, Mono-(4-Methyl Octyl) Ester (Minch) (13C4, 99%) 100 Ug/Ml In Mtbe is a high-purity, isotopically labeled analytical standard essential for precise quantitative analysis. This compound, provided as a certified reference material in a ready-to-use methyl tert-butyl ether (MTBE) solution, is critical for ensuring accuracy and traceability in sensitive detection methods. It is primarily required by analytical laboratories and research institutions in the environmental, pharmaceutical, and food safety sectors for method development, calibration, and quality control.

Application

• Internal Standard for Mass Spectrometry (MS): Used as a stable isotope-labeled internal standard for the accurate quantification of phthalates, plasticizers, or related metabolites via GC-MS or LC-MS/MS.
• Environmental Analysis: Calibration and quality assurance in the trace-level detection of industrial chemicals and their degradation products in water, soil, and air samples.
• Food Safety Testing: Employed in the analysis of food packaging migrants and contaminant monitoring to ensure regulatory compliance and consumer safety.
• Pharmaceutical Research: Supports pharmacokinetic and metabolism studies where precise measurement of specific compounds or their analogs is required.
• Method Development & Validation: Serves as a key reference material for developing, optimizing, and validating new analytical protocols.
• Forensic Toxicology: Aids in the identification and quantification of specific chemical markers in complex biological matrices.

Quality Control

This certified reference material is produced under strict quality control protocols to guarantee isotopic purity, concentration accuracy, and solution stability. Each batch is characterized using advanced techniques including NMR and mass spectrometry to confirm the 99% isotopic enrichment (13C4) and a precise concentration of 100 µg/mL in MTBE. A comprehensive Certificate of Analysis (COA) is supplied, detailing the analytical methods and results to ensure full traceability and compliance with ISO Guide 34 and ISO/IEC 17025 principles.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C (refrigerated). Due to the highly volatile nature of the MTBE solvent, ensure containers are securely sealed and stored in a well-ventilated area. For long-term stability, it is recommended to store the solution under inert atmosphere.
