Chemical Structure
Description
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.
2081-12-1 Tetra-tert-butoxyzirconium Tetra-tert-butyl zirconate ZTB Zirconium tert-butanolate Zirconium(IV) tert-butoxide (CAS 2081-12-1) is a high-purity analytical reference standard with the molecular formula C16H36O4Zr and a molecular weight of 383.68 g/mol.
Structurally, 2081-12-1 Tetra-tert-butoxyzirconium Tetra-tert-butyl zirconate ZTB Zirconium tert-butanolate Zirconium(IV) tert-butoxide (C16H36O4Zr) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of -1.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 383.68 g/mol, it falls into the moderately-high-molecular-weight range. 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.
