4-Methyl-2-(methylsulfanyl)-7-[3-(methylsulfanyl)phenyl]-5H,6H,7H-pyrrolo[2,3-d]pyrimidine CAS 338416-20-9

Description

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.

CATO supplies 4-Methyl-2-(methylsulfanyl)-7-[3-(methylsulfanyl)phenyl]-5H,6H,7H-pyrrolo[2,3-d]pyrimidine (CAS 338416-20-9), a certified reference material (molecular formula C15H17N3S2, MW 303.45 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 4-Methyl-2-(methylsulfanyl)-7-[3-(methylsulfanyl)phenyl]-5H,6H,7H-pyrrolo[2,3-d]pyrimidine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 303.45 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.
