Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Chloro(triphenylphosphine)rhodium.
Chloro(triphenylphosphine)rhodium (CAS 13822-79-2) is a high-purity analytical reference standard with the molecular formula C18H15ClPRh and a molecular weight of 400.64 g/mol.
Structurally, Chloro(triphenylphosphine)rhodium (C18H15ClPRh) contains organophosphorus functionality, chlorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 400.64 g/mol, it falls into the moderately-high-molecular-weight range. 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.
CATO manufactures Chloro(triphenylphosphine)rhodium 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.
