Chemical Structure

(3-Oxopentan-2-yl)triphenylphosphonium bromide CAS 111114-34-2 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (3-Oxopentan-2-yl)triphenylphosphonium bromide.

(3-Oxopentan-2-yl)triphenylphosphonium bromide (CAS 111114-34-2), molecular formula C23H24OPBr and molecular weight 427.32 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (3-Oxopentan-2-yl)triphenylphosphonium bromide (C23H24OPBr) contains a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.5, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 427.32 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), (3-Oxopentan-2-yl)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.
