Description
CATO manufactures 3-[2-(2-Ethoxyethoxy)ethoxy]thiophene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
3-[2-(2-Ethoxyethoxy)ethoxy]thiophene (CAS 138625-91-9), molecular formula C10H16O3S and molecular weight 216.30 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-[2-(2-Ethoxyethoxy)ethoxy]thiophene (C10H16O3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
