Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 224.21 g/mol gives Diethyl pyridazine-3,4-dicarboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Diethyl pyridazine-3,4-dicarboxylate (CAS 16082-13-6), molecular formula C10H12N2O4 and molecular weight 224.21 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Diethyl pyridazine-3,4-dicarboxylate (C10H12N2O4) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 224.21 g/mol, it falls into the medium-molecular-weight range. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
