Chemical Structure

Silicic acid, AR CAS 1343-98-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 78.10 g/mol gives Silicic acid, AR distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Silicic acid, AR (CAS 1343-98-2) is a high-purity analytical reference standard with the molecular formula H2O3Si and a molecular weight of 78.10 g/mol.

Owing to an inorganic composition, Silicic acid, AR is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 78.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
