1-(1-Chloro-3,4-dihydronaphthalen-2-yl)-N-(2,4-difluorophenyl)methanimine CAS 861208-84-6 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(1-Chloro-3,4-dihydronaphthalen-2-yl)-N-(2,4-difluorophenyl)methanimine.

1-(1-Chloro-3,4-dihydronaphthalen-2-yl)-N-(2,4-difluorophenyl)methanimine (CAS 861208-84-6) is a high-purity analytical reference standard with the molecular formula C17H12ClF2N and a molecular weight of 303.73 g/mol.

Structurally, 1-(1-Chloro-3,4-dihydronaphthalen-2-yl)-N-(2,4-difluorophenyl)methanimine (C17H12ClF2N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 303.73 g/mol, it falls into the moderately-high-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-(1-Chloro-3,4-dihydronaphthalen-2-yl)-N-(2,4-difluorophenyl)methanimine 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.
