Description
As a certified reference material (CRM), (7-Methoxybenzo[b]thiophen-5-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.
(7-Methoxybenzo[b]thiophen-5-yl)methanol (CAS 1388034-19-2), molecular formula C10H10O2S and molecular weight 194.25 g/mol, is a CATO reference standard with documented purity and traceability.
(7-Methoxybenzo[b]thiophen-5-yl)methanol (C10H10O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
