Chemical Structure
Description
Ethyl benzo[b]thiophen-3-ylcarbamate (CAS 78676-16-1), molecular formula C11H11NO2S and molecular weight 221.28 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Ethyl benzo[b]thiophen-3-ylcarbamate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 221.28 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Ethyl benzo[b]thiophen-3-ylcarbamate 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.
