Where it is used
- Naphthoate ester with an ortho bromide for cross-coupling.
- Cross-coupling (Buchwald-Hartwig, Suzuki, Sonogashira) at the halogen-bearing position
- Nucleophilic aromatic substitution where the halogen acts as the leaving group
Reading the specification
For aromatic halides, regiochemistry is the specification: the position of the halogen relative to the other substituents decides which site reacts first and how fast, so a positional isomer is a different product, not a grade variant. Two further lines matter: purity by GC, because residual isomeric halide carries through the coupling, and water, which hydrolyses benzylic halides and fouls palladium-catalysed steps.
Packaging and supply
Supplied in research quantities from 1 g and 5 g through 25 g and 100 g, with scale-up to bulk packed under nitrogen or argon where the product allows it. Every lot ships with a batch COA and the current SDS, FOB or CIF against destination. If you need a specific assay method, a water limit, an enantiomeric purity figure or a metal-residue limit, state it at enquiry stage – the batch documentation is issued against the specification you agree.
Handling: Use gloves, eye protection and local ventilation. Avoid dust generation, keep containers closed when not in use, and refer to the SDS for first aid, storage and disposal.
