2-Imino-5,6-dimethyl-2,3-dihydropyrimidin-4(1h)-one CAS 3977-23-9

Description

Owing to an amide group, a hydroxyl group, an ether linkage, an aromatic ring system, 2-Imino-5,6-dimethyl-2,3-dihydropyrimidin-4(1h)-one is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 139.16 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).

2-Imino-5,6-dimethyl-2,3-dihydropyrimidin-4(1h)-one (CAS 3977-23-9), molecular formula C6H9N3O and molecular weight 139.16 g/mol, is a CATO reference standard with documented purity and traceability.

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.

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.
