Description

1,4-Benzene-D4-Diamine is a deuterated analog of para-phenylenediamine, where four hydrogen atoms are replaced by deuterium, a stable hydrogen isotope. This isotopic labeling is critical for applications requiring enhanced analytical precision and metabolic stability studies. It is primarily utilized by researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors for use as a stable-isotope labeled internal standard, tracer, or building block in deuterated compounds.

Application

• Internal Standard for Mass Spectrometry (LC-MS, GC-MS) in quantitative bioanalytical methods.
• Deuterated Tracer in metabolic pathway and pharmacokinetic studies within pharmaceutical R&D.
• Precursor for synthesizing deuterated polymers and advanced organic electronic materials.
• Building block in the development of deuterated active pharmaceutical ingredients (APIs) and agrochemicals.
• NMR spectroscopy studies to elucidate molecular structure and reaction mechanisms.
• Stable isotope labeling in fundamental chemical and biochemical research.

Quality Control

Our 1,4-Benzene-D4-Diamine is produced and tested under strict quality management systems. Each batch undergoes comprehensive analysis to ensure high chemical purity and isotopic enrichment, with specifications typically meeting or exceeding 98% chemical purity and 98 atom % D. A detailed Certificate of Analysis (COA) providing batch-specific data for identity, purity, and isotopic content is supplied with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and light-sensitive; containers must be kept tightly sealed and under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent oxidation and moisture uptake.
