2-Chloro-2-fluoroethanol CAS 13891-54-8 chemical structure

Description

2-Chloro-2-fluoroethanol (CAS 13891-54-8) is a high-purity analytical reference standard with the molecular formula C2H4ClFO and a molecular weight of 98.50 g/mol.

The molecular framework of 2-Chloro-2-fluoroethanol (C2H4ClFO) is characterized by a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), 2-Chloro-2-fluoroethanol 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.
