Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Chloro-6-[(E)-2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl](4-chlorophenyl)methylidene}hydrazin-1-yl]pyridazine.
CATO supplies 3-Chloro-6-[(E)-2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl](4-chlorophenyl)methylidene}hydrazin-1-yl]pyridazine (CAS 321432-44-4), a certified reference material (molecular formula C17H9Cl3F3N5, MW 446.64 g/mol) for analytical method development and quality control.
Structurally, 3-Chloro-6-[(E)-2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl](4-chlorophenyl)methylidene}hydrazin-1-yl]pyridazine (C17H9Cl3F3N5) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 446.64 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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-6-[(E)-2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl](4-chlorophenyl)methylidene}hydrazin-1-yl]pyridazine 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.
