(3-Chloro-5-fluorophenyl)(m-tolyl)methanol CAS 842140-70-9

Description

Compared with other compounds in its class, the molecular weight of 250.70 g/mol gives (3-Chloro-5-fluorophenyl)(m-tolyl)methanol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(3-Chloro-5-fluorophenyl)(m-tolyl)methanol (CAS 842140-70-9), molecular formula C14H12ClFO and molecular weight 250.70 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, an ether linkage, fluorine/chlorine substitution, a polycyclic aromatic system, (3-Chloro-5-fluorophenyl)(m-tolyl)methanol is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 250.70 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), (3-Chloro-5-fluorophenyl)(m-tolyl)methanol 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.
