Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Fluorobenzo[b]thiophene-2-carbaldehyde.
4-Fluorobenzo[b]thiophene-2-carbaldehyde (CAS 698367-31-6), molecular formula C9H5FOS and molecular weight 180.20 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 4-Fluorobenzo[b]thiophene-2-carbaldehyde is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 180.20 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.
CATO manufactures 4-Fluorobenzo[b]thiophene-2-carbaldehyde under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
