Chemical Structure
Description
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 N-Boc-2-bromopyrrole, in hexane - 25% w/v (CAS 117657-37-1), a certified reference material (molecular formula C9H12BrNO2, MW 246.10 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution, N-Boc-2-bromopyrrole, in hexane - 25% w/v is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 246.10 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).
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.
