FBA31YJ60R 543-80-6 Barium acetate Acetic acid, barium salt Barium di(acetate) Acetic acid, barium salt (2:1) Barium diacetate Caswell No. 068A CCRIS 7240 EINECS 208-849-0 NSC 75794 Octan barnaty [Czech] Octan barnaty UNII-FBA31YJ60R (CAS 543-80-6) is a high-purity analytical reference standard with the molecular formula C4H6BaO4 and a molecular weight of 255.42 g/mol.
Structurally, FBA31YJ60R 543-80-6 Barium acetate Acetic acid, barium salt Barium di(acetate) Acetic acid, barium salt (2:1) Barium diacetate Caswell No. 068A CCRIS 7240 EINECS 208-849-0 NSC 75794 Octan barnaty [Czech] Octan barnaty UNII-FBA31YJ60R (C4H6BaO4) contains a carbohydrate-derived structure. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 255.42 g/mol, it falls into the medium-molecular-weight range.
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.
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.
