Description

Mono-(4-Methyl-7-Carboxyoctyl) Phthalate (Ring-1,2-13C2, Dicarboxyl-13C2,99%) 100Ug/Ml Mtbe is a high-purity, isotopically labeled internal standard critical for advanced analytical quantification. This compound provides unmatched accuracy and reliability in trace-level analysis by compensating for matrix effects and instrument variability. It is an essential reagent for research and quality control laboratories in the pharmaceutical, environmental, and metabolomics fields that require precise measurement of phthalate metabolites or related compounds.

Application

• Quantitative Mass Spectrometry: Serves as a stable isotope-labeled internal standard for the accurate LC-MS/MS or GC-MS quantification of phthalate metabolites in complex biological matrices.
• Biomedical & Clinical Research: Enables precise studies on human exposure to phthalates, supporting toxicology, pharmacokinetics, and biomarker discovery research.
• Environmental Monitoring: Used in the analysis of water, soil, and air samples to track environmental contamination and assess ecological impact with high specificity.
• Pharmaceutical Impurity Profiling: Aids in the detection and quantification of potential genotoxic impurities or degradation products in drug substances and products.
• Food Safety & Regulatory Testing: Supports compliance testing for phthalate migration from packaging materials into foodstuffs, adhering to global safety standards.
• Metabolomics & Biomarker Validation: Facilitates absolute quantification in targeted metabolomic workflows for validating disease biomarkers related to endocrine disruption.

Quality Control

Every batch of this isotopically labeled standard is manufactured and verified under strict quality systems to ensure identity, purity, and isotopic enrichment specifications are met. Comprehensive analysis, including NMR and High-Resolution Mass Spectrometry (HRMS), confirms the 99% 13C isotopic purity and chemical integrity. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting batch-specific data.

Storage

Preserve in the original tightly closed container, protected from light. Store at controlled room temperature (15-25°C) or as indicated on the label. Due to its high volatility and preparation in methyl tert-butyl ether (MTBE), ensure containers are kept upright in a well-ventilated area away from heat and ignition sources. For long-term stability, consider storage under inert atmosphere.
