Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-[1-(6-chloroimidazo[2,1-b][1,3]thiazol-5-yl)sulfonylindol-3-yl]ethanamine oxalic acid (CAS 1883548-85-3), molecular formula C15H27ClN4O2S2C2H2O4 and molecular weight 485.01 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 2-[1-(6-chloroimidazo[2,1-b][1,3]thiazol-5-yl)sulfonylindol-3-yl]ethanamine oxalic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 485.01 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
