Chemical Structure
Description
As a certified reference material (CRM), 1-(2-Amino-3-thienyl)ethanone 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.
CATO supplies 1-(2-Amino-3-thienyl)ethanone (CAS 892127-08-1), a certified reference material (molecular formula C6H7NOS, MW 141.19 g/mol) for analytical method development and quality control.
Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system, 1-(2-Amino-3-thienyl)ethanone is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 141.19 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.
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.
