1-((5-Bromothiophen-2-yl)methyl)-3-phenylurea CAS 1241554-57-3

Description

Compared with other compounds in its class, the molecular weight of 311.20 g/mol gives 1-((5-Bromothiophen-2-yl)methyl)-3-phenylurea distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-((5-Bromothiophen-2-yl)methyl)-3-phenylurea (CAS 1241554-57-3), molecular formula C12H11BrN2OS and molecular weight 311.20 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution, 1-((5-Bromothiophen-2-yl)methyl)-3-phenylurea is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 311.20 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
