2-Amino-4-phenyl-5-thiocyanato-thiophene-3-carboxylic acid ethyl ester CAS 304646-76-2

Description

The occurrence of 2-Amino-4-phenyl-5-thiocyanato-thiophene-3-carboxylic acid ethyl ester is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2-Amino-4-phenyl-5-thiocyanato-thiophene-3-carboxylic acid ethyl ester (CAS 304646-76-2), a certified reference material (molecular formula C14H12N2O2S2, MW 304.39 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-Amino-4-phenyl-5-thiocyanato-thiophene-3-carboxylic acid ethyl ester is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 304.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

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.
