Di-tert-butyl(isopropyl)phosphine CAS 25032-49-9

Description

Compared with other compounds in its class, the molecular weight of 188.29 g/mol gives Di-tert-butyl(isopropyl)phosphine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Di-tert-butyl(isopropyl)phosphine (CAS 25032-49-9) is a high-purity analytical reference standard with the molecular formula C11H25P and a molecular weight of 188.29 g/mol.

Structurally, Di-tert-butyl(isopropyl)phosphine (C11H25P) contains organophosphorus functionality. 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 188.29 g/mol, it falls into the medium-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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures Di-tert-butyl(isopropyl)phosphine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
