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.
tert-Butyl (2-(but-3-yn-1-yloxy)ethyl)carbamate (CAS 1187357-12-5), molecular formula C11H19NO3 and molecular weight 213.27 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, tert-Butyl (2-(but-3-yn-1-yloxy)ethyl)carbamate is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 213.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures tert-Butyl (2-(but-3-yn-1-yloxy)ethyl)carbamate 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.
