Benzo[d][1,3]dioxol-2-one

Benzo[d][1,3]dioxol-2-one is a cyclic carbonate heterocycle offered at min. 95 % purity, with CAS number 2171-74-6 and empirical formula C₇H₄O₃. It has a molar mass of 136,1 g/mol and features a fused benzodioxolone framework of interest in organic synthesis and biochemical intermediate chemistry. Supplied in a 5 g pack, the material is suited to laboratory applications that require a compact oxygen-rich scaffold for ring-opening, derivatisation, or incorporation into larger target structures. Researchers employ such reagents when developing fine chemicals, exploring heterocyclic reactivity, or preparing specialised intermediates under controlled conditions. Specification details from manufacturer Carl ROTH assist with reaction planning, identity confirmation, and documentation in regulated or method-driven environments. The defined molecular formula and purity grade support reproducible bench work in academic and industrial settings focused on small-molecule synthesis. This product integrates into standard chemical and biochemical workflows where a clearly identified benzo-fused dioxolone building block and practical pack size are required for screening and intermediate preparation.
