Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (3-Ethoxy-3-oxopropyl)triphenylphosphonium Bromide.
(3-Ethoxy-3-oxopropyl)triphenylphosphonium Bromide (CAS 42843-94-7) is a high-purity analytical reference standard with the molecular formula C23H24O2PBr and a molecular weight of 443.32 g/mol.
Owing to a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, bromine substitution, (3-Ethoxy-3-oxopropyl)triphenylphosphonium Bromide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 443.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures (3-Ethoxy-3-oxopropyl)triphenylphosphonium Bromide 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.
