1-Bromopyrene | CAS 1714-29-0

A monobrominated pyrene building block for constructing extended aromatic structures, offering a position-defined reaction handle on a four-ring scaffold used in molecular materials research.

CAS1714-29-0
Molecular formulaC16H9Br
Molecular weight281.15 g/mol

Product overview

Pyrene provides a fused four-ring aromatic framework. Bromination at position 1 creates a site for further functionalization without replacing that extended core. This structure distinguishes the material from parent pyrene and dibrominated derivatives. Qualification for optical or electronic material research should address aromatic impurity composition as well as the intended reaction chemistry.

Application context

Published chemistry uses 1-bromopyrene in the construction of pyrene-annulated furans through pyryne intermediates. It is also catalogued as a building block for organic semiconductor research. These applications use the molecule as a precursor to a designed structure. Evaluate the synthesized derivative in the target optical or device system, while specifying parent pyrene, additional brominated species and route-relevant metals in the incoming-material review.

Chemistry and synthetic role

The fused aromatic core is retained as a structural element; the position-1 bromine enables elaboration of that core.

Quality review

Establish monobromopyrene identity

Confirm the pyrene skeleton and the position-1 substitution pattern.

Review aromatic impurity composition

Resolve pyrene and relevant dibrominated species to protect the intended functionality.

Match residue controls to materials work

For sensitive optical experiments, agree metal and nonvolatile-residue tests tied to the downstream process.

Preparing a specification

Specify 1-bromopyrene identity, aromatic impurity separation, assay and any metals or nonvolatile residue criteria required by the target material.

Packaging and storage

Confirm container compatibility, closure and net weight for the selected grade and destination. Follow the actual supplier SDS and batch label for storage and transport.

Documentation

Request the batch COA, SDS and analytical methods covering the agreed purchasing specification. Confirm which supporting chromatograms and application-specific records are available from the selected manufacturer.

Procurement questions

Is it an organic semiconductor device material as supplied?

It is a building block; the final derivative and device require their own evaluation.

Why distinguish dibromopyrene?

A second bromine changes functionality and can introduce additional coupling sites.

Does colour alone establish suitability?

Use chromatographic and structural results; optical suitability depends on the designed material.
