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 Methyl N-{3-[(4-chlorophenyl)methoxy]thiophen-2-yl}carbamate.
CATO supplies Methyl N-{3-[(4-chlorophenyl)methoxy]thiophen-2-yl}carbamate (CAS 339009-49-3), a certified reference material (molecular formula C13H12ClNO3S, MW 297.76 g/mol) for analytical method development and quality control.
The molecular framework of Methyl N-{3-[(4-chlorophenyl)methoxy]thiophen-2-yl}carbamate (C13H12ClNO3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
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.
