Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 2-Amino-4,8,8-trimethyl-4,5,6,7-tetrahydro-4,7-methanobenzo[b]thiophene-3-carboxylate.
CATO supplies Ethyl 2-Amino-4,8,8-trimethyl-4,5,6,7-tetrahydro-4,7-methanobenzo[b]thiophene-3-carboxylate (CAS 190718-16-2), a certified reference material (molecular formula C15H21NO2S, MW 279.40 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl 2-Amino-4,8,8-trimethyl-4,5,6,7-tetrahydro-4,7-methanobenzo[b]thiophene-3-carboxylate (C15H21NO2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
As a certified reference material (CRM), Ethyl 2-Amino-4,8,8-trimethyl-4,5,6,7-tetrahydro-4,7-methanobenzo[b]thiophene-3-carboxylate 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.
