Chemical Structure
Description
The occurrence of 1-(3-Fluorophenyl)urea is closely related to an amide group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-(3-Fluorophenyl)urea (CAS 770-19-4) is a high-purity analytical reference standard with the molecular formula C7H7FN2O and a molecular weight of 154.14 g/mol.
Based on its molecular formula C7H7FN2O, 1-(3-Fluorophenyl)urea contains an amide group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 154.14 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.
As a certified reference material (CRM), 1-(3-Fluorophenyl)urea meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
