Chemical Structure

tert-Butyl 2-(tributylphosphoranylidene)acetate CAS 252039-91-1 chemical structure

Description

The occurrence of tert-Butyl 2-(tributylphosphoranylidene)acetate is closely related to organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

tert-Butyl 2-(tributylphosphoranylidene)acetate (CAS 252039-91-1), molecular formula C18H37O2P and molecular weight 316.46 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, tert-Butyl 2-(tributylphosphoranylidene)acetate (C18H37O2P) contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 316.46 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.

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.
