25510-41-2 29H,31H-Phthalocyanine, lithium salt (1:2) 29H,31H-Phthalocyanine, dilithium salt Dilithium phthalocyanine NSC 338962 Phthalocyanine, dilithium salt (CAS 25510-41-2) is a high-purity analytical reference standard with the molecular formula C32H54Li2N8 and a molecular weight of 564.71 g/mol.
Structurally, 25510-41-2 29H,31H-Phthalocyanine, lithium salt (1:2) 29H,31H-Phthalocyanine, dilithium salt Dilithium phthalocyanine NSC 338962 Phthalocyanine, dilithium salt (C32H54Li2N8) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 564.71 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
