Chemical Structure
Description
The occurrence of 5-Methoxy-6-methylpyrimidine-4-carbonitrile is closely related to an amide group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-Methoxy-6-methylpyrimidine-4-carbonitrile (CAS 114969-83-4) is a high-purity analytical reference standard with the molecular formula C7H7N3O and a molecular weight of 149.15 g/mol.
Structurally, 5-Methoxy-6-methylpyrimidine-4-carbonitrile (C7H7N3O) contains an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 149.15 g/mol, it falls into the low-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
