1188AE 2-Amino-4-ethyl-5-methyl-3-thiophenecarboxamide 350996-89-3 C8H12N2OS CAS 350996-89-3

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.

1188AE 2-Amino-4-ethyl-5-methyl-3-thiophenecarboxamide 350996-89-3 C8H12N2OS (CAS 350996-89-3) is a high-purity analytical reference standard with the molecular formula C8H12N2OS and a molecular weight of 184.26 g/mol.

The molecular framework of 1188AE 2-Amino-4-ethyl-5-methyl-3-thiophenecarboxamide 350996-89-3 C8H12N2OS (C8H12N2OS) 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. 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).

As a certified reference material (CRM), 1188AE 2-Amino-4-ethyl-5-methyl-3-thiophenecarboxamide 350996-89-3 C8H12N2OS 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.
