Chemical Structure
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 (3-Chlorophenyl)(5-methylthiophen-2-yl)methanol (CAS 944652-71-5), a certified reference material (molecular formula C12H11ClOS, MW 238.73 g/mol) for analytical method development and quality control.
(3-Chlorophenyl)(5-methylthiophen-2-yl)methanol (C12H11ClOS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), (3-Chlorophenyl)(5-methylthiophen-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.
