3,4-Dihydro-4-oxothieno[2,3-<I>d</I>]pyrimidine CAS 14080-50-3 chemical structure

Description

The occurrence of 3,4-Dihydro-4-oxothieno[2,3-<I>d</I>]pyrimidine is closely related to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3,4-Dihydro-4-oxothieno[2,3-<I>d</I>]pyrimidine (CAS 14080-50-3), molecular formula C6H8N2OS and molecular weight 156.21 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3,4-Dihydro-4-oxothieno[2,3-<I>d</I>]pyrimidine (C6H8N2OS) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), 3,4-Dihydro-4-oxothieno[2,3-<I>d</I>]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.
