Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
N-[4-(2-bromoacetyl)-3,5-dimethyl-phenyl]acetamide (CAS 136382-02-0), molecular formula C12H20BrNO2 and molecular weight 290.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-[4-(2-bromoacetyl)-3,5-dimethyl-phenyl]acetamide (C12H20BrNO2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
