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.
CATO supplies AB-FUBINACA 2-Fluorobenzyl Isomer (CAS 1185282-16-9), a certified reference material (molecular formula C20H21FN4O2, MW 368.40 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, AB-FUBINACA 2-Fluorobenzyl Isomer is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 368.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
