5-Methoxy-4-[(4-methoxyphenyl)sulfanyl]-2-(methylsulfanyl)pyrimidine CAS 338955-62-7 chemical structure

Description

The occurrence of 5-Methoxy-4-[(4-methoxyphenyl)sulfanyl]-2-(methylsulfanyl)pyrimidine is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 5-Methoxy-4-[(4-methoxyphenyl)sulfanyl]-2-(methylsulfanyl)pyrimidine (CAS 338955-62-7), a certified reference material (molecular formula C13H14N2O2S2, MW 294.39 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 5-Methoxy-4-[(4-methoxyphenyl)sulfanyl]-2-(methylsulfanyl)pyrimidine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 294.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

As a certified reference material (CRM), 5-Methoxy-4-[(4-methoxyphenyl)sulfanyl]-2-(methylsulfanyl)pyrimidine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
