Chemical Structure
Description
As a certified reference material (CRM), 1-(5-methylthiophen-2-yl)ethan-1-ol 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.
1-(5-methylthiophen-2-yl)ethan-1-ol (CAS 34878-40-5), molecular formula C7H10OS and molecular weight 142.22 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(5-methylthiophen-2-yl)ethan-1-ol (C7H10OS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
