5-((2-Amino-5-nitrophenyl)thio)-4-chloropyridazin-3(2H)-one CAS 62688-67-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-((2-Amino-5-nitrophenyl)thio)-4-chloropyridazin-3(2H)-one.

5-((2-Amino-5-nitrophenyl)thio)-4-chloropyridazin-3(2H)-one (CAS 62688-67-9) is a high-purity analytical reference standard with the molecular formula C10H7ClN4O3S and a molecular weight of 298.71 g/mol.

The molecular framework of 5-((2-Amino-5-nitrophenyl)thio)-4-chloropyridazin-3(2H)-one (C10H7ClN4O3S) is characterized by a nitrogen-containing heterocyclic scaffold, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

As a certified reference material (CRM), 5-((2-Amino-5-nitrophenyl)thio)-4-chloropyridazin-3(2H)-one 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.
