Chemical Structure

1-(2,2-Dichloro-1,1-Difluoroethoxy)-4-Isocyanatobenzene CAS 55225-96-2 chemical structure

Description

1-(2,2-Dichloro-1,1-Difluoroethoxy)-4-Isocyanatobenzene (CAS 55225-96-2) is a high-purity analytical reference standard with the molecular formula C9H5Cl2F2NO2 and a molecular weight of 268.04 g/mol.

The molecular framework of 1-(2,2-Dichloro-1,1-Difluoroethoxy)-4-Isocyanatobenzene (C9H5Cl2F2NO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

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), 1-(2,2-Dichloro-1,1-Difluoroethoxy)-4-Isocyanatobenzene 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.
