Chemical Structure

Carbamic acid, [[[3-chloro-4-(4-chlorophenoxy)phenyl]amino]thioxomethyl]-, 2-methoxyethyl ester CAS 301352-30-7 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 Carbamic acid, [[[3-chloro-4-(4-chlorophenoxy)phenyl]amino]thioxomethyl]-, 2-methoxyethyl ester.

CATO supplies Carbamic acid, [[[3-chloro-4-(4-chlorophenoxy)phenyl]amino]thioxomethyl]-, 2-methoxyethyl ester (CAS 301352-30-7), a certified reference material (molecular formula C17H16Cl2N2O4S, MW 415.29 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, Carbamic acid, [[[3-chloro-4-(4-chlorophenoxy)phenyl]amino]thioxomethyl]-, 2-methoxyethyl ester is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 415.29 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.

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.
