Tert-butyl 3-amino-6-methylthieno[2,3-b]pyridine-2-carboxylate CAS 625366-89-4

Description

Compared with other compounds in its class, the molecular weight of 264.34 g/mol gives Tert-butyl 3-amino-6-methylthieno[2,3-b]pyridine-2-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Tert-butyl 3-amino-6-methylthieno[2,3-b]pyridine-2-carboxylate (CAS 625366-89-4), molecular formula C13H16N2O2S and molecular weight 264.34 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Tert-butyl 3-amino-6-methylthieno[2,3-b]pyridine-2-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 264.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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), Tert-butyl 3-amino-6-methylthieno[2,3-b]pyridine-2-carboxylate 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.
