Product overview & key benefits
In phenyl-d5-boronic acid all five ring hydrogens are replaced by deuterium. Coupling it in a Suzuki reaction transfers a C₆D₅ group, which is used to make deuterated drug candidates (where C–D bonds can slow metabolism), isotope-labeled internal standards for mass spectrometry, and deuterated host and emitter materials that extend OLED lifetime.
For deuterated products, isotopic enrichment (atom % D) matters as much as chemical purity. Note that the formula on the current page (C₆H₇BO₂) is the non-deuterated compound; the deuterated formula is C₆H₂D₅BO₂.

Selection & comparison
Choosing the right phenyl-d5-boronic acid grade
| Your requirement | What usually works |
|---|---|
| Deuterated drug candidates | Specify atom % D and chemical purity |
| OLED materials | Specify enrichment, purity and metal limits |
| Analytical standards | Small packs with enrichment data |
| Replacing an existing supplier | Send your current TDS or COA; we quote against the parameters you approve |
Packaging & storage
Packaging
25 kg drums; smaller packs for evaluation on request.
Storage
Keep containers closed in a cool, dry place; avoid moisture, which can exchange with and degrade the material.
From first email to approved supply
Name the end use
Drug candidate, standard or OLED: enrichment and purity limits follow from it.
Compare the numbers that matter
Chemical purity, isotopic enrichment (atom % D, by NMR or MS), anhydride and moisture.
Confirm the analytical method
Agree how atom % D is measured before you compare offers.
Trial, then lock the spec
Run a sample in your own process and keep the approved lot COA as the reference for contract limits.
