(3-Aminothieno[2,3-b]pyridin-2-yl)(3,4-dihydroxyphenyl)methanone CAS 1087648-20-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (3-Aminothieno[2,3-b]pyridin-2-yl)(3,4-dihydroxyphenyl)methanone.

(3-Aminothieno[2,3-b]pyridin-2-yl)(3,4-dihydroxyphenyl)methanone (CAS 1087648-20-1), molecular formula C14H10N2O3S and molecular weight 286.31 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, (3-Aminothieno[2,3-b]pyridin-2-yl)(3,4-dihydroxyphenyl)methanone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 286.31 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
