Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, tert-butyl N-[(5-cyanothiophen-2-yl)methyl]carbamate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 238.31 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.
tert-butyl N-[(5-cyanothiophen-2-yl)methyl]carbamate (CAS 302341-67-9), molecular formula C11H14N2O2S and molecular weight 238.31 g/mol, is a CATO reference standard with documented purity and traceability.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures tert-butyl N-[(5-cyanothiophen-2-yl)methyl]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.
