(2-(4-Nitrophenyl)-2-oxoethyl)triphenylphosphonium bromide CAS 17730-93-7

Description

The occurrence of (2-(4-Nitrophenyl)-2-oxoethyl)triphenylphosphonium bromide is closely related to a steroid core, an amide group, a phosphonate group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(2-(4-Nitrophenyl)-2-oxoethyl)triphenylphosphonium bromide (CAS 17730-93-7), molecular formula C26H21NO3P and molecular weight 426.42 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (2-(4-Nitrophenyl)-2-oxoethyl)triphenylphosphonium bromide (C26H21NO3P) contains a steroid core, an amide group, a phosphonate group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 17.0, corresponding to approximately 17 ring(s) or double-bond equivalent(s). With a molecular weight of 426.42 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.

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), (2-(4-Nitrophenyl)-2-oxoethyl)triphenylphosphonium bromide 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.
