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.
CATO supplies 2-(ethyl(3-methyl-4-((5-nitrothiazol-2-yl)azo)phenyl)amino)ethanol 7781-23-9 AR-1C9230 (CAS 7781-23-9), a certified reference material (molecular formula C7H10N2O2, MW 154.17 g/mol) for analytical method development and quality control.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 2-(ethyl(3-methyl-4-((5-nitrothiazol-2-yl)azo)phenyl)amino)ethanol 7781-23-9 AR-1C9230 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 154.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
CATO manufactures 2-(ethyl(3-methyl-4-((5-nitrothiazol-2-yl)azo)phenyl)amino)ethanol 7781-23-9 AR-1C9230 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.
