Chemical Structure

Tetrakis(1-methoxy-2-methyl-2-propoxy)hafnium(iv) CAS 309915-48-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 591.05 g/mol gives Tetrakis(1-methoxy-2-methyl-2-propoxy)hafnium(iv) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Tetrakis(1-methoxy-2-methyl-2-propoxy)hafnium(iv) (CAS 309915-48-8) is a high-purity analytical reference standard with the molecular formula C20H44HfO8 and a molecular weight of 591.05 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Tetrakis(1-methoxy-2-methyl-2-propoxy)hafnium(iv) is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 591.05 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.
