LAP Lithium Phenyl(2,4,6-trimethylbenzoyl)phosphinate Lithium PTMB phosphinate P-Phenyl-P-(2,4,6-trimethylbenzoyl)phosphinic acid 85073-19-4 (CAS 85073-19-4) is a high-purity analytical reference standard with the molecular formula C16H16LiO3P and a molecular weight of 294.21 g/mol.

Structurally, LAP Lithium Phenyl(2,4,6-trimethylbenzoyl)phosphinate Lithium PTMB phosphinate P-Phenyl-P-(2,4,6-trimethylbenzoyl)phosphinic acid 85073-19-4 (C16H16LiO3P) contains a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 294.21 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
