Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 2-{[(4-chlorobenzoyl)oxy]ethanimidoyl}-1,3-thiazole 866050-61-5 KS-00002WRJ is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 280.73 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).
2-{[(4-chlorobenzoyl)oxy]ethanimidoyl}-1,3-thiazole 866050-61-5 KS-00002WRJ (CAS 866050-61-5), molecular formula C12H9ClN2O2S and molecular weight 280.73 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
