3-Aminobenzo[b]thiophene-2-carbaldehyde CAS 39827-51-5

Description

Compared with other compounds in its class, the molecular weight of 177.22 g/mol gives 3-Aminobenzo[b]thiophene-2-carbaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-Aminobenzo[b]thiophene-2-carbaldehyde (CAS 39827-51-5), molecular formula C9H7NOS and molecular weight 177.22 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-Aminobenzo[b]thiophene-2-carbaldehyde (C9H7NOS) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
