Chemical Structure
Description
The occurrence of Tin(iv) 2,3-naphthalocyanine dichloride is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Tin(iv) 2,3-naphthalocyanine dichloride (CAS 26857-61-4), molecular formula C48H24Cl2N8Sn and molecular weight 902.37 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C48H24Cl2N8Sn, Tin(iv) 2,3-naphthalocyanine dichloride contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 902.37 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
