Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5666-12-6 Phosphorous acid tripyrrolidide Tripyrrolidinophosphine Tris(N,N-tetramethylene)phosphorous acid triamide (CAS 5666-12-6), molecular formula C12H24N3P and molecular weight 241.31 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5666-12-6 Phosphorous acid tripyrrolidide Tripyrrolidinophosphine Tris(N,N-tetramethylene)phosphorous acid triamide (C12H24N3P) is characterized by a nitrile group, organophosphorus functionality. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures 5666-12-6 Phosphorous acid tripyrrolidide Tripyrrolidinophosphine Tris(N,N-tetramethylene)phosphorous acid triamide 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.
