Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (E)-{[6-(4-chlorophenyl)imidazo[2,1-b][1,3]thiazol-5-yl]methylidene}[(4-nitrophenyl)methoxy]amine.
(E)-{[6-(4-chlorophenyl)imidazo[2,1-b][1,3]thiazol-5-yl]methylidene}[(4-nitrophenyl)methoxy]amine (CAS 338404-56-1) is a high-purity analytical reference standard with the molecular formula C19H13ClN4O3S and a molecular weight of 412.85 g/mol.
(E)-{[6-(4-chlorophenyl)imidazo[2,1-b][1,3]thiazol-5-yl]methylidene}[(4-nitrophenyl)methoxy]amine (C19H13ClN4O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), (E)-{[6-(4-chlorophenyl)imidazo[2,1-b][1,3]thiazol-5-yl]methylidene}[(4-nitrophenyl)methoxy]amine 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.
