Chemical Structure
Description
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.
(E)-N-({4-[(2-chloro-1,3-thiazol-5-yl)methoxy]phenyl}methylidene)hydroxylamine 3P-036 478032-47-2 (CAS 478032-47-2), molecular formula C11H9ClN2O2S and molecular weight 268.72 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (E)-N-({4-[(2-chloro-1,3-thiazol-5-yl)methoxy]phenyl}methylidene)hydroxylamine 3P-036 478032-47-2 (C11H9ClN2O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
