Benzene-1,3,5-tricarbaldehyde | CAS 3163-76-6

A threefold symmetric trialdehyde node for covalent organic framework research, providing three condensation sites whose integrity and stoichiometric availability influence network assembly.

CAS3163-76-6
Molecular formulaC9H6O3
Molecular weight162.14 g/mol

Product overview

Three aldehyde groups project from alternating positions on a benzene ring. The compact 1,3,5 geometry creates a node rather than a linear linker. This makes aldehyde integrity particularly important: partially oxidized or otherwise modified material can change effective functionality even when the main aromatic structure remains recognizable.

Application context

Framework synthesis combines this trialdehyde with suitable complementary condensation partners to construct extended organic networks. It is used in COF research, where linker geometry and functional-group balance help define the intended structure. Procurement should specify the trialdehyde identity, assay basis and relevant lower-functionality impurities. The resulting framework still requires its own crystallinity, porosity and application testing.

Chemistry and synthetic role

Aldehyde condensation connects three positions around the aromatic core; the chosen reaction partner determines the linkage chemistry.

Quality review

Confirm all three aldehydes

Combine structural identification with a method sensitive to changes in aldehyde functionality.

Review oxidation-related components

Agree reporting of acid-containing or other modified species relevant to network formation.

Define water and effective assay

Match water and active-monomer basis to the selected condensation system.

Preparing a specification

Specify 1,3,5-trialdehyde identity, active-monomer assay, modified-aldehyde impurities and water relevant to the chosen framework chemistry.

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 this a linear linker?

It is a three-connected node with aldehydes at positions 1,3,5.

Why care about partially oxidized material?

It can reduce or change the available condensation functionality.

Does monomer purity specify COF porosity?

No. The assembled framework must be characterized separately.
