Disperse Yellow 1 CAS 119-15-3

Description

Compared with other compounds in its class, the molecular weight of 275.22 g/mol gives Disperse Yellow 1 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Disperse Yellow 1 (CAS 119-15-3), molecular formula C12H9N3O5 and molecular weight 275.22 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C12H9N3O5, Disperse Yellow 1 contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 275.22 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), Disperse Yellow 1 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.
