CAS 1343-98-2 — Silicic acid, -100 mesh, for chromatographic applications

Silicic acid is a weakly acidic form of silicon dioxide used primarily as a stationary phase in chromatographic separations, particularly in column and thin-layer chromatography. It is also employed in analytical chemistry for its ability to retain polar compounds effectively. This product is silicic acid with a particle size of -100 mesh (150 µm), meeting rigorous standards for chromatographic applications. It has a CAS number of 1343-98-2, molecular formula H₄O₄Si, and a molecular weight of 96.1149 g/mol. Store at room temperature (+20°C). No signal word applies under standard handling conditions. Molekula supplies silicic acid from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
