Description

Cyclohexane-1,2-Dicarboxylic Acid, Di-(4-Methyl Octyl) Ester (Dinch) (13C4, 99%) 100 Ug/Ml In Mtbe is a high-purity, isotopically labeled standard of the widely used plasticizer DINCH. This product is specifically formulated as a 100 µg/mL solution in methyl tert-butyl ether (MTBE), providing a ready-to-use analytical reference material for precise quantification and method development. It is an essential tool for laboratories requiring high-accuracy trace analysis in complex matrices, particularly for compliance testing and research into material migration. Primary users include analytical chemists and quality control specialists in the polymer, food contact material, and environmental monitoring industries.

Application

• Internal Standard for GC-MS/LC-MS Analysis: Used for the accurate quantification of non-labeled DINCH and related plasticizers via isotope dilution mass spectrometry.
• Migration Studies in Food Contact Materials: Critical for testing the migration levels of plasticizers from packaging into food simulants to ensure regulatory compliance (e.g., EU 10/2011).
• Polymer Additive Research: Serves as a tracer in studies investigating the leaching, degradation, and distribution of plasticizers within polymer matrices.
• Environmental and Biomonitoring Analysis: Enables sensitive detection and measurement of DINCH metabolites or the parent compound in environmental samples (water, soil) and human biomonitoring studies.
• Method Development and Validation: Provides a stable, characterized reference point for developing and validating new analytical methods for phthalate alternatives.
• Quality Control of Consumer Products: Used to verify the absence or controlled presence of specific plasticizers in toys, medical devices, and other sensitive products.

Quality Control

This certified reference material is produced under strict quality-controlled conditions to ensure isotopic enrichment and chemical purity. Each batch is characterized using advanced analytical techniques including NMR and High-Resolution Mass Spectrometry to confirm the 13C4 isotopic labeling (99%) and concentration accuracy. A comprehensive Certificate of Analysis (COA) is supplied, detailing the exact concentration, solvent verification, isotopic purity, and analytical method data, supporting its use in GLP/GMP-compliant laboratories.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C (refrigerated) to maintain solution stability and minimize solvent evaporation. The product is highly volatile due to the MTBE solvent and should be handled in a well-ventilated area. Allow the solution to reach room temperature before opening to prevent condensation.
