Chemical Structure
Description
As a certified reference material (CRM), 2-({2-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]hydrazin-1-yl}methylidene)cyclohexane-1,3-dione 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 2-({2-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]hydrazin-1-yl}methylidene)cyclohexane-1,3-dione (CAS 439097-27-5), a certified reference material (molecular formula C13H11ClF3N3O2, MW 333.69 g/mol) for analytical method development and quality control.
Structurally, 2-({2-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]hydrazin-1-yl}methylidene)cyclohexane-1,3-dione (C13H11ClF3N3O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 333.69 g/mol, it falls into the moderately-high-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.
