Chemical Structure
Description
The occurrence of 1-(3-(Trifluoromethyl)phenyl)thiourea is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-(3-(Trifluoromethyl)phenyl)thiourea (CAS 1736-70-5) is a high-purity analytical reference standard with the molecular formula C8H7F3N2S and a molecular weight of 220.21 g/mol.
1-(3-(Trifluoromethyl)phenyl)thiourea (C8H7F3N2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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-(Trifluoromethyl)phenyl)thiourea 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.
