3-Amino-4-methylthieno[2,3-b]pyridine-2-carboxamide CAS 498580-73-7

Description

As a certified reference material (CRM), 3-Amino-4-methylthieno[2,3-b]pyridine-2-carboxamide 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.

3-Amino-4-methylthieno[2,3-b]pyridine-2-carboxamide (CAS 498580-73-7), molecular formula C9H9N3OS and molecular weight 207.25 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 3-Amino-4-methylthieno[2,3-b]pyridine-2-carboxamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 207.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
