Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2-(7-Methyl-5-oxo-2-(p-tolyl)imidazo[1,2-a]pyrimidin-8(5H)-yl)acetic acid (CAS 902836-45-7), a certified reference material (molecular formula C16H15N3O3, MW 297.31 g/mol) for analytical method development and quality control.
Structurally, 2-(7-Methyl-5-oxo-2-(p-tolyl)imidazo[1,2-a]pyrimidin-8(5H)-yl)acetic acid (C16H15N3O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 297.31 g/mol, it falls into the medium-molecular-weight range. 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.
