Deuterium-Labeled Compounds

They are molecules in which one or more hydrogen atoms have been replaced by deuterium (²H or D), a stable non-radioactive isotope of hydrogen — used for labeling in analytical and research applications. :contentReference[oaicite:1]{index=1}

Pharmaffiliates offers over 10,000 high-purity deuterium-labeled compounds in flexible pack sizes such as 1 mg, 10 mg — and they can also supply custom pack sizes on request. :contentReference[oaicite:2]{index=2}

They are suitable for use in mass spectrometry as internal standards, for studying reaction mechanisms or biosynthetic pathways, for metabolic-stability studies in drug development, and in spectroscopy (NMR, IR) or enzymology applications. :contentReference[oaicite:3]{index=3}

Yes — Pharmaffiliates provides custom synthesis services for deuterated compounds. Their “Small Molecules Synthesis” division can design and produce small complex molecules (including stable isotopes) from milligram to gram scale. :contentReference[oaicite:4]{index=4}

Yes — Pharmaffiliates claims to supply high-purity deuterated standards suitable for analytical and regulatory use, implying that they maintain quality standards consistent with reference-standard supply. :contentReference[oaicite:5]{index=5}

Catalog compounds are available in small pack sizes (1 mg, 10 mg) and generally ready in stock; custom synthesis is typically offered on request. Pricing and lead time depend on the complexity of the molecule and required isotopic labeling — you need to send a quote request for specific timelines and cost. :contentReference[oaicite:6]{index=6}

They are suitable for analytical method development, bioanalysis via LC-MS/MS or GC-MS, impurity profiling, metabolite tracking, stability studies, and structure elucidation — i.e. a wide range of research and regulated environments. :contentReference[oaicite:7]{index=7}

Pharmaffiliates’ services include large-molecule synthesis capabilities and scaled operations. While their deuterated-compounds page highlights small pack sizes, their custom synthesis capability suggests they can handle larger scale projects — but you'd need to specify your required quantity when requesting a quote. :contentReference[oaicite:8]{index=8}

You can fill out the “Enquire Now” / contact form on Pharmaffiliates’ website, providing details like compound name, quantity, and whether you need a COA — a sales representative will respond, usually within a short time. :contentReference[oaicite:9]{index=9}

Pharmaffiliates claims to supply “high-purity deuterium-labeled compounds” and offers documentation such as COAs. Their products are promoted as suitable reference standards and for applications like LC-MS, GC-MS, NMR, and impurity profiling. :contentReference[oaicite:10]{index=10}
