Description

Compared with other compounds in its class, the molecular weight of 211.21 g/mol gives 3-Amino-4-fluorobenzo[b]thiophene-2-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-Amino-4-fluorobenzo[b]thiophene-2-carboxylic acid (CAS 874800-63-2) is a high-purity analytical reference standard with the molecular formula C9H6FNO2S and a molecular weight of 211.21 g/mol.

The molecular framework of 3-Amino-4-fluorobenzo[b]thiophene-2-carboxylic acid (C9H6FNO2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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

As a certified reference material (CRM), 3-Amino-4-fluorobenzo[b]thiophene-2-carboxylic acid 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.
