Chemical Structure
Description
The occurrence of n-Isopropyl-2-(thieno[2,3-d]pyrimidin-4-ylamino)acetamide 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 n-Isopropyl-2-(thieno[2,3-d]pyrimidin-4-ylamino)acetamide (CAS 923748-93-0), a certified reference material (molecular formula C11H14N4OS, MW 250.32 g/mol) for analytical method development and quality control.
The molecular framework of n-Isopropyl-2-(thieno[2,3-d]pyrimidin-4-ylamino)acetamide (C11H14N4OS) 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 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.
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), n-Isopropyl-2-(thieno[2,3-d]pyrimidin-4-ylamino)acetamide 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.
