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 (4,5-Dibromo-6-oxopyridazin-1(6H)-yl)methyl 2-chloroacetate.
(4,5-Dibromo-6-oxopyridazin-1(6H)-yl)methyl 2-chloroacetate (CAS 866018-26-0), molecular formula C7H5Br2ClN2O3 and molecular weight 360.39 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (4,5-Dibromo-6-oxopyridazin-1(6H)-yl)methyl 2-chloroacetate (C7H5Br2ClN2O3) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system. 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures (4,5-Dibromo-6-oxopyridazin-1(6H)-yl)methyl 2-chloroacetate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
