Chemical Structure
Description
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.
(1R,3r)-3-(8-bromo-1-chloropyrrolo[1,2-a]pyrazin-6-yl)-1-methylcyclobutan-1-ol (CAS 936901-74-5) is a high-purity analytical reference standard with the molecular formula C12H12BrClN2O and a molecular weight of 315.59 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, (1R,3r)-3-(8-bromo-1-chloropyrrolo[1,2-a]pyrazin-6-yl)-1-methylcyclobutan-1-ol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 315.59 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
