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)-4-chloro-N'-ethylidenebenzohydrazide.
CATO supplies (E)-4-chloro-N'-ethylidenebenzohydrazide (CAS 68180-99-4), a certified reference material (molecular formula C9H9ClN2O, MW 196.63 g/mol) for analytical method development and quality control.
(E)-4-chloro-N'-ethylidenebenzohydrazide (C9H9ClN2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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)-4-chloro-N'-ethylidenebenzohydrazide 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.
