Chemical Structure

6-Amino-3-methylpyrimidin-4(3H)-one CAS 1122-46-9 chemical structure

Description

6-Amino-3-methylpyrimidin-4(3H)-one (CAS 1122-46-9), molecular formula C5H7N3O and molecular weight 125.13 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 6-Amino-3-methylpyrimidin-4(3H)-one (C5H7N3O) contains an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 125.13 g/mol, it falls into the low-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).

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 manufactures 6-Amino-3-methylpyrimidin-4(3H)-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
