Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
N-(7-acetyl-2,3-dihydrobenzo[b][1,4]dioxin-6-yl)-2-chloroacetamide (CAS 444065-67-2), molecular formula C12H12ClNO4 and molecular weight 269.68 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C12H12ClNO4, N-(7-acetyl-2,3-dihydrobenzo[b][1,4]dioxin-6-yl)-2-chloroacetamide contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 269.68 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.
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.
