2-Ethyl-5,6-dimethylthieno[2,3-d]pyrimidin-4-ol CAS 433716-50-8

Description

The occurrence of 2-Ethyl-5,6-dimethylthieno[2,3-d]pyrimidin-4-ol is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2-Ethyl-5,6-dimethylthieno[2,3-d]pyrimidin-4-ol (CAS 433716-50-8), a certified reference material (molecular formula C10H12N2OS, MW 208.28 g/mol) for analytical method development and quality control.

The molecular framework of 2-Ethyl-5,6-dimethylthieno[2,3-d]pyrimidin-4-ol (C10H12N2OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
