Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 651.54 g/mol gives Pigment Orange 34 (Technical Grade) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Pigment Orange 34 (Technical Grade) (CAS 15793-73-4), a certified reference material (molecular formula C34H28Cl2N8O2, MW 651.54 g/mol) for analytical method development and quality control.
Structurally, Pigment Orange 34 (Technical Grade) (C34H28Cl2N8O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 24.0, corresponding to approximately 24 ring(s) or double-bond equivalent(s). With a molecular weight of 651.54 g/mol, it falls into the high-molecular-weight range. 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.
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.
