Chemical Structure

(T-4)-Dichloro[1,1′-(1,3-propanediyl)bis[1,1-diphenylphosphine-κP]]cobalt CAS 18078-25-6 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 (T-4)-Dichloro[1,1′-(1,3-propanediyl)bis[1,1-diphenylphosphine-κP]]cobalt.

CATO supplies (T-4)-Dichloro[1,1′-(1,3-propanediyl)bis[1,1-diphenylphosphine-κP]]cobalt (CAS 18078-25-6), a certified reference material (molecular formula C27H26Cl2CoP2, MW 542.28 g/mol) for analytical method development and quality control.

Based on its molecular formula C27H26Cl2CoP2, (T-4)-Dichloro[1,1′-(1,3-propanediyl)bis[1,1-diphenylphosphine-κP]]cobalt contains organophosphorus functionality, chlorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 542.28 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
