Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (7-Fluorobenzo[b]thiophen-2-yl)methanol (CAS 1135283-78-1), a certified reference material (molecular formula C9H7FOS, MW 182.21 g/mol) for analytical method development and quality control.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, (7-Fluorobenzo[b]thiophen-2-yl)methanol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 182.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), (7-Fluorobenzo[b]thiophen-2-yl)methanol 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.
