Description

3,6,3-Nonylphenol diethoxylate-13C6 (363-NP2EO-13C6), also known as 2-{2-[4-(3,6-Dimethyl-3-heptyl)phenoxy]ethoxy}ethanol-13C6, is a carbon-13 labeled isotopologue of a nonylphenol ethoxylate surfactant. This compound is of critical importance for analytical and research applications where precise tracking and quantification are required. It serves as an internal standard or tracer for scientists and quality control laboratories in environmental monitoring, toxicology studies, and industrial process analysis.

Application

• Internal Standard for Mass Spectrometry (MS): Used for the accurate quantification of nonylphenol ethoxylates (NPEOs) in complex matrices via LC-MS or GC-MS.
• Environmental Fate and Transport Studies: Employed as a stable isotopic tracer to study the biodegradation, adsorption, and environmental behavior of NPEO surfactants.
• Metabolic Pathway Analysis: Facilitates research into the metabolic breakdown of alkylphenol ethoxylates in biological systems.
• Quality Control & Method Development: Essential for developing and validating robust analytical methods in contract research organizations (CROs) and regulatory testing labs.
• Industrial Process Monitoring: Used to trace surfactant efficiency, distribution, and residues in manufacturing processes.
• Toxicological Research: Aids in precise dosing and tracking in studies investigating the endocrine-disrupting potential of NPEOs.

Quality Control

Every batch of our isotopically labeled materials is produced and verified under stringent conditions to ensure high chemical and isotopic purity. Quality is confirmed via advanced analytical techniques including NMR, HPLC, and High-Resolution Mass Spectrometry. A comprehensive Certificate of Analysis (COA) detailing isotopic enrichment (atom % 13C), chemical purity, and analytical chromatograms is provided with each shipment to support your research integrity.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at controlled room temperature (15-25°C) to minimize oxidation. Keep the container in a cool, dry, and well-ventilated place.
