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 N'-[(1E)-{[(2-chloro-6-fluorophenyl)methoxy]amino}methylidene]-2-(5-phenyl-2H-1,2,3,4-tetrazol-2-yl)acetohydrazide.
CATO supplies N'-[(1E)-{[(2-chloro-6-fluorophenyl)methoxy]amino}methylidene]-2-(5-phenyl-2H-1,2,3,4-tetrazol-2-yl)acetohydrazide (CAS 338791-39-2), a certified reference material (molecular formula C17H15ClFN7O2, MW 403.80 g/mol) for analytical method development and quality control.
Structurally, N'-[(1E)-{[(2-chloro-6-fluorophenyl)methoxy]amino}methylidene]-2-(5-phenyl-2H-1,2,3,4-tetrazol-2-yl)acetohydrazide (C17H15ClFN7O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, 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 403.80 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
