5-tert-Butyl 3-ethyl 2-amino-4H,5H,6H,7H-thieno[3,2-c]pyridine-3,5-dicarboxylate CAS 1101856-88-5

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.

5-tert-Butyl 3-ethyl 2-amino-4H,5H,6H,7H-thieno[3,2-c]pyridine-3,5-dicarboxylate (CAS 1101856-88-5), molecular formula C15H22N2O4S and molecular weight 326.41 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C15H22N2O4S, 5-tert-Butyl 3-ethyl 2-amino-4H,5H,6H,7H-thieno[3,2-c]pyridine-3,5-dicarboxylate contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 326.41 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 5-tert-Butyl 3-ethyl 2-amino-4H,5H,6H,7H-thieno[3,2-c]pyridine-3,5-dicarboxylate 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.
