Chemical Structure

5-Methoxy-4,6-dimethylpyrimidine CAS 85331-94-8 chemical structure

Description

5-Methoxy-4,6-dimethylpyrimidine (CAS 85331-94-8) is a high-purity analytical reference standard with the molecular formula C7H10N2O and a molecular weight of 138.17 g/mol.

Owing to an amide group, a hydroxyl group, an ether linkage, an aromatic ring system, 5-Methoxy-4,6-dimethylpyrimidine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 138.17 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).

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.
