Description

2-Hedta (2-Hydroxyethyl-D4, 98%) is a high-purity, deuterated derivative of the well-known chelating agent HEDTA, specifically labeled on the ethylenediamine backbone. This deuteration is critical for applications requiring isotopic labeling to study reaction mechanisms, metabolic pathways, or to serve as an internal standard in quantitative mass spectrometry. It is primarily sought after by researchers and manufacturers in the pharmaceutical, agrochemical, and advanced material sectors for use in analytical chemistry, NMR spectroscopy, and the development of labeled compounds.

Application

• Internal Standard for Mass Spectrometry (MS): Used as a quantitative reference standard in LC-MS and GC-MS analysis due to its stable isotopic label, improving accuracy in pharmacokinetic and metabolomic studies.
• NMR Spectroscopy Solvent & Reagent: Serves as a deuterated agent or a precursor for synthesizing other deuterated compounds, aiding in complex structural elucidation without proton interference.
• Mechanistic Studies & Tracing: Employed in chemical and biochemical research to trace reaction pathways and investigate metal ion chelation mechanisms using isotopic labeling techniques.
• Pharmaceutical Intermediate: Acts as a building block for the synthesis of deuterated drug candidates, which can offer improved metabolic stability and pharmacokinetic profiles.
• Specialty Chemical Synthesis: Utilized in the production of advanced materials and specialty chemicals where isotopic purity is required for specific functional properties.

Quality Control

Every batch of 2-Hedta (2-Hydroxyethyl-D4, 98%) is manufactured and analyzed under strict quality management protocols to ensure identity, purity, and isotopic enrichment. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request, detailing key parameters such as assay, isotopic purity (D-enrichment), and impurity profiles.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect stability and purity.
