Heterocyclic building block
Serves as a functionalised pyrazole scaffold in organic synthesis, where the aldehyde and aryl-bromide handles allow further elaboration into more complex molecules.
Pharmaceutical-intermediate research
Used in medicinal-chemistry and discovery programmes to construct pyrazole-containing candidate compounds and intermediates. TSS supplies it for research and development use.
Aldehyde-based transformations
The reactive carbaldehyde group participates in condensations, reductive aminations and related reactions to introduce imines, alcohols and other functional groups.
Cross-coupling chemistry
The 4-bromophenyl substituent provides a site for palladium-catalysed cross-coupling reactions such as Suzuki, Heck and related couplings to build biaryl and extended structures.
Laboratory reagent
Acts as a reference and synthetic reagent for method development and structure-activity studies in academic and industrial laboratories.
