Chemical Structure

(4,5-Dichloro-6-oxopyridazin-1(6H)-yl)methyl 4-methylbenzoate CAS 178211-04-6 chemical structure

Description

The molecular framework of (4,5-Dichloro-6-oxopyridazin-1(6H)-yl)methyl 4-methylbenzoate (C13H10Cl2N2O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide 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).

(4,5-Dichloro-6-oxopyridazin-1(6H)-yl)methyl 4-methylbenzoate (CAS 178211-04-6), molecular formula C13H10Cl2N2O3 and molecular weight 313.14 g/mol, is a CATO reference standard with documented purity and traceability.

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), (4,5-Dichloro-6-oxopyridazin-1(6H)-yl)methyl 4-methylbenzoate 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.
