Description
1-(4-CHLORO-3-NITROPHENYL)ETHAN-1-ONE 1-(4-CHLORO-3-NITROPHENYL)ETHANONE 3'-NITRO-4'-CHLORO ACETOPHENONE 4'-CHLORO-3'-NITROACETOPHENONE 4-CHLORO-3'-NITROACETOPHENONE 4-Chloro-3-nitroacetophenone 5465-65-6 AS04028 PARAGOS 440051 RARECHEM AK HB 0025 (CAS 5465-65-6) is a high-purity analytical reference standard with the molecular formula C8H12ClNO3 and a molecular weight of 205.64 g/mol.
Based on its molecular formula C8H12ClNO3, 1-(4-CHLORO-3-NITROPHENYL)ETHAN-1-ONE 1-(4-CHLORO-3-NITROPHENYL)ETHANONE 3'-NITRO-4'-CHLORO ACETOPHENONE 4'-CHLORO-3'-NITROACETOPHENONE 4-CHLORO-3'-NITROACETOPHENONE 4-Chloro-3-nitroacetophenone 5465-65-6 AS04028 PARAGOS 440051 RARECHEM AK HB 0025 contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 205.64 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
