1-{2,4,5-trimethylthieno[2,3-d]pyrimidin-6-yl}ethan-1-one CAS 941083-97-2

Description

The occurrence of 1-{2,4,5-trimethylthieno[2,3-d]pyrimidin-6-yl}ethan-1-one is closely related to 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 1-{2,4,5-trimethylthieno[2,3-d]pyrimidin-6-yl}ethan-1-one (CAS 941083-97-2), a certified reference material (molecular formula C11H20N2OS, MW 228.35 g/mol) for analytical method development and quality control.

Structurally, 1-{2,4,5-trimethylthieno[2,3-d]pyrimidin-6-yl}ethan-1-one (C11H20N2OS) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 228.35 g/mol, it falls into the medium-molecular-weight range. 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), 1-{2,4,5-trimethylthieno[2,3-d]pyrimidin-6-yl}ethan-1-one 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.
