4-Bromothiazole, min. 95 %, 25 g

4-Bromothiazole is a heterocyclic building block supplied at a minimum purity of 95 %, with CAS number 34259-99-9 and empirical formula C₃H₂BrNS. The molar mass is 164,02 g/mol and the density is 1,839 g/cm³, giving clear quantitative data for dosing and volume-related calculations in the laboratory. This variant is packed as 250 g, a practical quantity for preparative synthesis, intermediate stock and repeated experimental series that require a brominated thiazole core. The defined C₃H₂BrNS structure supports further functionalisation in organic and medicinal chemistry programmes under standard research conditions. Provided by manufacturer Carl ROTH, the product forms part of the chemicals and biochemicals range and is positioned for professional laboratory users. Key specifications—minimum 95 % purity, CAS 34259-99-9, empirical formula C₃H₂BrNS, molar mass 164,02 g/mol and density 1,839 g/cm³—facilitate accurate documentation, inventory control and reaction planning. The 250 g pack size offers a balance between availability and manageable handling for bench and kilo-lab style work. Careful weighing and established laboratory procedures are recommended throughout use. With transparent chemical identity and physical properties, this 4-bromothiazole grade suits organised synthetic workflows that depend on a reliable bromothiazole intermediate.
