2,2'-Spirobi[benzo[d][1,3,2]dioxasilole] CAS 181-88-4

Description

Compared with other compounds in its class, the molecular weight of 244.28 g/mol gives 2,2'-Spirobi[benzo[d][1,3,2]dioxasilole] distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2,2'-Spirobi[benzo[d][1,3,2]dioxasilole] (CAS 181-88-4) is a high-purity analytical reference standard with the molecular formula C12H8O4Si and a molecular weight of 244.28 g/mol.

Based on its molecular formula C12H8O4Si, 2,2'-Spirobi[benzo[d][1,3,2]dioxasilole] contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 244.28 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
