Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 201.61 g/mol gives 2-(4-Chloro-3-nitrophenyl)ethanol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-(4-Chloro-3-nitrophenyl)ethanol (CAS 89979-05-5), molecular formula C8H8ClNO3 and molecular weight 201.61 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 2-(4-Chloro-3-nitrophenyl)ethanol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 201.61 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-(4-Chloro-3-nitrophenyl)ethanol 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.
