Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 187.63 g/mol gives 1-(3-Aminophenyl)urea hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-(3-Aminophenyl)urea hydrochloride (CAS 59690-88-9) is a high-purity analytical reference standard with the molecular formula C7H9N3OHCl and a molecular weight of 187.63 g/mol.
Based on its molecular formula C7H9N3OHCl, 1-(3-Aminophenyl)urea hydrochloride contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 187.63 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.
