3533AF 5-(2-Chloro-acetyl)-1,3-dihydro-benzoimidazol-2-one 93202-41-6 C9H7ClN2O2 CAS 93202-41-6

Description

3533AF 5-(2-Chloro-acetyl)-1,3-dihydro-benzoimidazol-2-one 93202-41-6 C9H7ClN2O2 (CAS 93202-41-6), molecular formula C9H7ClN2O2 and molecular weight 210.62 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 3533AF 5-(2-Chloro-acetyl)-1,3-dihydro-benzoimidazol-2-one 93202-41-6 C9H7ClN2O2 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 210.62 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

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.
