Zincon is an analytical-grade metal indicator offered at minimum 95 % purity, p.a., with empirical formula C₂₀H₁₅N₄NaO₆S and molar mass 462,41 g/mol (CAS 62625-22-3). EG number 263-651-1 supports clear identification in quality systems and chemical inventories. Categories such as analytical chemicals and metal indicators reflect its typical use for monitoring selected metal ions under controlled conditions. Product from manufacturer Carl ROTH arrives in a compact glass pack suited to precise dispensing on the analytical bench. Documented assay, formula and CAS data help laboratories maintain traceable reagent lists and method descriptions. The solid form is convenient for preparing indicator solutions according to established protocols. This grade is aimed at research and routine analytical environments that require a reliable p.a. zincon portion with transparent composition data and no unspecified performance claims.
