Description

Mono-(8-Carboxynonyl) 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 is specifically designed for use in mass spectrometry, providing unmatched accuracy in trace-level analysis of phthalate metabolites and related compounds. It is an essential reagent for environmental testing laboratories, clinical research facilities, and industrial quality control units requiring precise and reliable calibration standards to meet stringent regulatory demands.

Application

• Internal Standard for LC-MS/MS: Primary application for the accurate quantification of phthalate metabolites and plasticizer degradation products in complex matrices.
• Environmental Monitoring: Calibration standard for analyzing phthalate contamination in water, soil, and air samples to comply with environmental protection agency (EPA) guidelines.
• Biomonitoring & Clinical Research: Used in human exposure studies to measure urinary or serum levels of phthalates, supporting toxicological and epidemiological research.
• Food Safety & Packaging Testing: Ensures accurate measurement of phthalate migration from packaging materials into foodstuffs.
• Pharmaceutical Impurity Profiling: Aids in the detection and quantification of potential genotoxic impurities (PGIs) derived from phthalates in drug substances and products.
• Method Development & Validation: Serves as a critical tool for developing, optimizing, and validating robust analytical methods in accredited laboratories.
• Forensic Analysis: Supports precise material identification and source tracking in forensic science investigations.

Quality Control

Every batch of our isotopically labeled standards is produced and verified under strict quality management protocols. The product is characterized using advanced techniques including NMR and High-Resolution Mass Spectrometry to confirm the position-specific 13C enrichment (99%) and chemical purity. Certificates of Analysis (COA) are provided with each unit, detailing batch-specific data on isotopic purity, chemical purity, concentration, and solvent verification. Our quality system is designed to support GLP/GMP-compliant laboratory workflows.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below for long-term stability. The solution in methyl tert-butyl ether (MTBE) is highly volatile and a strong acid/organic solvent; handle in a well-ventilated fume hood and keep away from heat, sparks, and open flames. Allow the vial to equilibrate to room temperature before opening to prevent moisture condensation.
