Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Trelagliptin Impurity 9.
CATO supplies Trelagliptin Impurity 9 (CAS 222978-03-2), a certified reference material (molecular formula C8H5BrFN, MW 214.03 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/bromine substitution, Trelagliptin Impurity 9 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 214.03 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
