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 (E)-N-(4-bromophenyl)-1-(pyridin-4-yl)methanimine.
(E)-N-(4-bromophenyl)-1-(pyridin-4-yl)methanimine (CAS 244301-83-5) is a high-purity analytical reference standard with the molecular formula C12H9BrN2 and a molecular weight of 261.12 g/mol.
Structurally, (E)-N-(4-bromophenyl)-1-(pyridin-4-yl)methanimine (C12H9BrN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 261.12 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.
As a certified reference material (CRM), (E)-N-(4-bromophenyl)-1-(pyridin-4-yl)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.
