Chemical Structure

ethyl 2-[(3-chloropropanoyl)amino]-5-methyl-4-phenylthiophene-3-carboxylate CAS 497091-41-5 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-[(3-chloropropanoyl)amino]-5-methyl-4-phenylthiophene-3-carboxylate.

ethyl 2-[(3-chloropropanoyl)amino]-5-methyl-4-phenylthiophene-3-carboxylate (CAS 497091-41-5) is a high-purity analytical reference standard with the molecular formula C17H18ClNO3S and a molecular weight of 351.85 g/mol.

The molecular framework of ethyl 2-[(3-chloropropanoyl)amino]-5-methyl-4-phenylthiophene-3-carboxylate (C17H18ClNO3S) is characterized by a steroid core, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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-[(3-chloropropanoyl)amino]-5-methyl-4-phenylthiophene-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.
