Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-[(2,4-Dichlorophenyl)methoxy]-N'-(pyridine-2-carboximidoyl)thiophene-2-carbohydrazide.
CATO supplies 3-[(2,4-Dichlorophenyl)methoxy]-N'-(pyridine-2-carboximidoyl)thiophene-2-carbohydrazide (CAS 339009-53-9), a certified reference material (molecular formula C18H14Cl2N4O2S, MW 421.30 g/mol) for analytical method development and quality control.
The molecular framework of 3-[(2,4-Dichlorophenyl)methoxy]-N'-(pyridine-2-carboximidoyl)thiophene-2-carbohydrazide (C18H14Cl2N4O2S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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-[(2,4-Dichlorophenyl)methoxy]-N'-(pyridine-2-carboximidoyl)thiophene-2-carbohydrazide 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.
