6-(Tert-butyl)-1,2-dihydrodiindeno[7,1-de:1',7'-fg][1,3,2]dioxaphosphocine CAS 2131111-57-2

Description

6-(Tert-butyl)-1,2-dihydrodiindeno[7,1-de:1',7'-fg][1,3,2]dioxaphosphocine (CAS 2131111-57-2), molecular formula C21H23O2P and molecular weight 338.38 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, 6-(Tert-butyl)-1,2-dihydrodiindeno[7,1-de:1',7'-fg][1,3,2]dioxaphosphocine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 338.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

As a certified reference material (CRM), 6-(Tert-butyl)-1,2-dihydrodiindeno[7,1-de:1',7'-fg][1,3,2]dioxaphosphocine 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.
