Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 242.23 g/mol gives Disperse Orange 3 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Disperse Orange 3 (CAS 730-40-5) is a high-purity analytical reference standard with the molecular formula C12H10N4O2 and a molecular weight of 242.23 g/mol.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Disperse Orange 3 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 242.23 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.
CATO manufactures Disperse Orange 3 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
