Chemical Structure

3-Chloro-4-fluoro-N'-hydroxybenzimidamide CAS 885963-77-9 chemical structure

Description

The occurrence of 3-Chloro-4-fluoro-N'-hydroxybenzimidamide is closely related to an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-Chloro-4-fluoro-N'-hydroxybenzimidamide (CAS 885963-77-9), molecular formula C7H6ClFN2O and molecular weight 188.59 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3-Chloro-4-fluoro-N'-hydroxybenzimidamide (C7H6ClFN2O) contains an amide group, a hydroxyl group, an ether linkage, 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 188.59 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 3-Chloro-4-fluoro-N'-hydroxybenzimidamide 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.
