Chemical Structure
Description
2-(2,5-DIchlorophenyl)indoline, HCl (CAS 1177321-77-5) is a high-purity analytical reference standard with the molecular formula C14H11Cl2NHCl and a molecular weight of 300.61 g/mol.
Based on its molecular formula C14H11Cl2NHCl, 2-(2,5-DIchlorophenyl)indoline, HCl contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 300.61 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
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.
