Acid Red 249 CAS 6416-66-6

Description

Compared with other compounds in its class, the molecular weight of 725.11 g/mol gives Acid Red 249 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Acid Red 249 (CAS 6416-66-6), a certified reference material (molecular formula C29H20ClN3O10S3Na, MW 725.11 g/mol) for analytical method development and quality control.

Based on its molecular formula C29H20ClN3O10S3Na, Acid Red 249 contains a salt form, a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 725.11 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), Acid Red 249 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.
