Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 3-Amino-5-(4-(tert-butyl)phenyl)thiophene-2-carboxamide is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 274.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
3-Amino-5-(4-(tert-butyl)phenyl)thiophene-2-carboxamide (CAS 306935-13-7), molecular formula C15H18N2OS and molecular weight 274.38 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
