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 (4,5-Dichlorothiophen-2-yl)methanol (CAS 89284-46-8), a certified reference material (molecular formula C5H4Cl2OS, MW 183.06 g/mol) for analytical method development and quality control.
(4,5-Dichlorothiophen-2-yl)methanol (C5H4Cl2OS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), (4,5-Dichlorothiophen-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.
