Chemical Structure
Description
The occurrence of 5-(4-Chlorobenzyl)furan-2-carboxylic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5-(4-Chlorobenzyl)furan-2-carboxylic acid (CAS 15045-73-5), a certified reference material (molecular formula C12H9ClO3, MW 236.65 g/mol) for analytical method development and quality control.
Structurally, 5-(4-Chlorobenzyl)furan-2-carboxylic acid (C12H9ClO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 236.65 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.
As a certified reference material (CRM), 5-(4-Chlorobenzyl)furan-2-carboxylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
