Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2Z)-4-(2,6-Dichlorophenoxy)-2-{[(2,4-difluorophenyl)amino](hydroxy)methylidene}-3-oxobutanenitrile.
(2Z)-4-(2,6-Dichlorophenoxy)-2-{[(2,4-difluorophenyl)amino](hydroxy)methylidene}-3-oxobutanenitrile (CAS 866154-58-7), molecular formula C17H10Cl2F2N2O3 and molecular weight 399.18 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (2Z)-4-(2,6-Dichlorophenoxy)-2-{[(2,4-difluorophenyl)amino](hydroxy)methylidene}-3-oxobutanenitrile (C17H10Cl2F2N2O3) 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 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 399.18 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.
As a certified reference material (CRM), (2Z)-4-(2,6-Dichlorophenoxy)-2-{[(2,4-difluorophenyl)amino](hydroxy)methylidene}-3-oxobutanenitrile 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.
