Chemical Structure

3-Hydroxy-7-iodobenzo[b]thiophene-2-carboxylic acid CAS 1934712-87-4 chemical structure

Description

The occurrence of 3-Hydroxy-7-iodobenzo[b]thiophene-2-carboxylic acid is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3-Hydroxy-7-iodobenzo[b]thiophene-2-carboxylic acid (CAS 1934712-87-4), a certified reference material (molecular formula C9H5IO3S, MW 320.10 g/mol) for analytical method development and quality control.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system, 3-Hydroxy-7-iodobenzo[b]thiophene-2-carboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 320.10 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).

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-Hydroxy-7-iodobenzo[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.
