Chemical Structure
Description
The occurrence of Methylene(2,4,6-tri-tert-butylphenyl)phosphane is closely related to organophosphorus functionality, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Methylene(2,4,6-tri-tert-butylphenyl)phosphane (CAS 84114-18-1) is a high-purity analytical reference standard with the molecular formula C19H31P and a molecular weight of 290.42 g/mol.
The molecular framework of Methylene(2,4,6-tri-tert-butylphenyl)phosphane (C19H31P) is characterized by organophosphorus functionality, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Methylene(2,4,6-tri-tert-butylphenyl)phosphane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
