Owing to an inorganic composition, Iron(III) arsenide is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 130.77 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
CATO supplies Iron(III) arsenide (CAS 12044-16-5), a certified reference material (molecular formula AsFe, MW 130.77 g/mol) for analytical method development and quality control.
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.
