N-(4-Oxo-6-phenylthieno[2,3-d]pyrimidin-3(4H)-yl)formamide CAS 111849-30-0

Description

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.

N-(4-Oxo-6-phenylthieno[2,3-d]pyrimidin-3(4H)-yl)formamide (CAS 111849-30-0) is a high-purity analytical reference standard with the molecular formula C13H9N3O2S and a molecular weight of 271.29 g/mol.

The molecular framework of N-(4-Oxo-6-phenylthieno[2,3-d]pyrimidin-3(4H)-yl)formamide (C13H9N3O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

As a certified reference material (CRM), N-(4-Oxo-6-phenylthieno[2,3-d]pyrimidin-3(4H)-yl)formamide 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.
