Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 204.65 g/mol gives 2'-Chloro-[1,1'-biphenyl]-4-ol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2'-Chloro-[1,1'-biphenyl]-4-ol (CAS 149950-35-6), a certified reference material (molecular formula C12H9ClO, MW 204.65 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 2'-Chloro-[1,1'-biphenyl]-4-ol is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 204.65 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.
As a certified reference material (CRM), 2'-Chloro-[1,1'-biphenyl]-4-ol 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.
