Description

1,3-Propanediamine-2,2-D2 2Hcl is a deuterium-labeled derivative of 1,3-propanediamine dihydrochloride, where two hydrogen atoms at the 2-position are replaced with deuterium (D). This compound is a critical tool for researchers requiring internal standards in mass spectrometry and for mechanistic studies in organic and medicinal chemistry, where tracking molecular pathways is essential. It is primarily utilized by scientists in pharmaceutical R&D, analytical chemistry, and advanced material science for applications such as metabolic pathway analysis, protein structure determination, and the synthesis of isotopically labeled compounds.

Application

• Internal Standard for Mass Spectrometry (MS): Serves as a high-purity, isotopically labeled internal standard for the accurate quantification of 1,3-propanediamine and related compounds in complex biological or chemical matrices via LC-MS or GC-MS.
• Metabolic Pathway Tracing: Used in pharmacokinetic and metabolic studies to trace the absorption, distribution, metabolism, and excretion (ADME) of drug candidates and biomolecules.
• NMR Spectroscopy Studies: Acts as a probe in Nuclear Magnetic Resonance (NMR) spectroscopy for investigating molecular structure, dynamics, and interactions without signal interference from protonated analogs.
• Synthesis of Deuterated Compounds: A key building block for the synthesis of more complex deuterium-labeled pharmaceuticals, agrochemicals, and specialty materials.
• Protein & Peptide Modification: Employed in bioconjugation chemistry and for modifying proteins or peptides to study structure-function relationships.
• Catalysis and Mechanistic Research: Utilized in catalytic studies to elucidate reaction mechanisms through kinetic isotope effect (KIE) experiments.

Quality Control

Every batch of 1,3-Propanediamine-2,2-D2 2Hcl is produced and analyzed under strict quality protocols to ensure high chemical purity and isotopic enrichment suitable for sensitive analytical applications. Our quality assurance includes comprehensive testing against established in-house specifications. A detailed Certificate of Analysis (COA) providing batch-specific data on purity, isotopic purity (D-enrichment), and impurities is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container should be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture uptake and decomposition.
