Présentation du produit & avantages clés
4-Formylphenylboronic acid carries two handles: the boronic acid couples to aryl halides in Suzuki–Miyaura reactions, and the aldehyde can then be reduced, oxidized, aminated or condensed. That makes it a common building block for biaryl pharmaceutical intermediates and for electronic materials such as OLED and liquid-crystal compounds.
Like other boronic acids, it can contain varying amounts of its cyclic anhydride (boroxine). The TDS states how assay is measured; agree the method before comparing offers.

Selection & comparaison
Choosing the right 4-FPBA grade
| Your requirement | What usually works |
|---|---|
| Pharmaceutical synthesis | Specify assay method and related-substance limits |
| Electronic materials | Specify purity and metal-ion limits |
| Process development | Start with a sample lot and lock the spec after your trial |
| Replacing an existing supplier | Send your current TDS or COA; we quote against the parameters you approve |
Emballage & stockage
Emballage
25 fûts de kg; smaller packs for evaluation on request.
Storage
Keep containers closed in a cool, dry place under inert gas if possible; the aldehyde slowly oxidizes in air.
Du premier e-mail à la fourniture approuvée
Name the end use
Pharma or electronics: purity and metal limits follow from it.
Compare the numbers that matter
Essai (HPLC or titration), anhydride content, moisture and the related substances that affect your coupling.
Protect the material
Store cool, dry and closed; the aldehyde oxidizes to the carboxylic acid over time.
Trial, then lock the spec
Run a sample in your own process and keep the approved lot COA as the reference for contract limits.
