Methyl 3-amino-4,5-dihydronaphtho[1,2-b]thiophene-2-carboxylate CAS 691393-99-4 chemical structure

Description

CATO supplies Methyl 3-amino-4,5-dihydronaphtho[1,2-b]thiophene-2-carboxylate (CAS 691393-99-4), a certified reference material (molecular formula C14H13NO2S, MW 259.32 g/mol) for analytical method development and quality control.

The molecular framework of Methyl 3-amino-4,5-dihydronaphtho[1,2-b]thiophene-2-carboxylate (C14H13NO2S) 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. 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.

As a certified reference material (CRM), Methyl 3-amino-4,5-dihydronaphtho[1,2-b]thiophene-2-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.
