Description

373-61-5 Boron trifluoride-acetic acid complex,35-36.5% BF3 MFCD00036359 Borate(1-), bis(acetato-.kappa.O)difluoro-, hydrogen fluoride (1:2:1), (T-4)- Borate(1-), bis(acetato-O)difluoro-, dihydrogen fluoride, ( beta-4)- Acetic acid boron trifluoride (2:1) (CAS 373-61-5), molecular formula BF3C2H4O2 and molecular weight 127.86 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, 373-61-5 Boron trifluoride-acetic acid complex,35-36.5% BF3 MFCD00036359 Borate(1-), bis(acetato-.kappa.O)difluoro-, hydrogen fluoride (1:2:1), (T-4)- Borate(1-), bis(acetato-O)difluoro-, dihydrogen fluoride, ( beta-4)- Acetic acid boron trifluoride (2:1) is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 127.86 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
