Chemical Structure

1-(2-Chloro-4-fluorophenyl)guanidine CAS 896720-31-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 187.60 g/mol gives 1-(2-Chloro-4-fluorophenyl)guanidine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1-(2-Chloro-4-fluorophenyl)guanidine (CAS 896720-31-3), a certified reference material (molecular formula C7H7ClFN3, MW 187.60 g/mol) for analytical method development and quality control.

Structurally, 1-(2-Chloro-4-fluorophenyl)guanidine (C7H7ClFN3) contains a nitrile group, fluorine/chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 187.60 g/mol, it falls into the medium-molecular-weight range. 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-Chloro-4-fluorophenyl)guanidine 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.
