594-31-0 Antimony, dichlorotriphenyl- Dichlorotriphenylantimony Antimony, triphenyldichloride BRN 4142072 Dichlorid trifenylantimonicny [Czech] Dichlorotriphenylstibine EINECS 209-834-1 NSC 179782 NSC 432 Stibine, triphenyl-, dichloride (6CI) Triphenylantimony dichloride Triphenylstibine dichloride Dichlorid trifenylantimonicny (CAS 594-31-0), molecular formula C18H33Cl2Sb and molecular weight 442.12 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 594-31-0 Antimony, dichlorotriphenyl- Dichlorotriphenylantimony Antimony, triphenyldichloride BRN 4142072 Dichlorid trifenylantimonicny [Czech] Dichlorotriphenylstibine EINECS 209-834-1 NSC 179782 NSC 432 Stibine, triphenyl-, dichloride (6CI) Triphenylantimony dichloride Triphenylstibine dichloride Dichlorid trifenylantimonicny (C18H33Cl2Sb) contains chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.5, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 442.12 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), 594-31-0 Antimony, dichlorotriphenyl- Dichlorotriphenylantimony Antimony, triphenyldichloride BRN 4142072 Dichlorid trifenylantimonicny [Czech] Dichlorotriphenylstibine EINECS 209-834-1 NSC 179782 NSC 432 Stibine, triphenyl-, dichloride (6CI) Triphenylantimony dichloride Triphenylstibine dichloride Dichlorid trifenylantimonicny 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.
