Chemical Structure

3-Chlorophenol CAS 108-43-0 chemical structure

Description

As a certified reference material (CRM), 3-Chlorophenol 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.

3-Chlorophenol (CAS 108-43-0), molecular formula C6H5ClO and molecular weight 128.56 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 3-Chlorophenol is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 128.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
