Chemical Structure

3-Sulfobenzaldehyde CAS 98-45-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 186.19 g/mol gives 3-Sulfobenzaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-Sulfobenzaldehyde (CAS 98-45-3) is a high-purity analytical reference standard with the molecular formula C7H6O4S and a molecular weight of 186.19 g/mol.

Structurally, 3-Sulfobenzaldehyde (C7H6O4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 186.19 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
