Chemical Structure
Description
As a certified reference material (CRM), (E)-1-[(1-Chloro-3,4-dihydronaphthalen-2-yl)methylidene]-2-phenylhydrazine 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.
CATO supplies (E)-1-[(1-Chloro-3,4-dihydronaphthalen-2-yl)methylidene]-2-phenylhydrazine (CAS 320423-97-0), a certified reference material (molecular formula C17H15ClN2, MW 282.77 g/mol) for analytical method development and quality control.
Structurally, (E)-1-[(1-Chloro-3,4-dihydronaphthalen-2-yl)methylidene]-2-phenylhydrazine (C17H15ClN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, 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 282.77 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
