Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 594.54 g/mol gives Reactive Orange 16 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Reactive Orange 16 (CAS 12225-88-6), molecular formula C20H17N3O11S3Na and molecular weight 594.54 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Reactive Orange 16 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 594.54 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
