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 1-(2-((2-Chlorobenzyl)thio)ethyl)-5-oxopyrrolidine-3-carboxylic acid.
1-(2-((2-Chlorobenzyl)thio)ethyl)-5-oxopyrrolidine-3-carboxylic acid (CAS 1440535-35-2) is a high-purity analytical reference standard with the molecular formula C14H16ClNO3S and a molecular weight of 313.80 g/mol.
Based on its molecular formula C14H16ClNO3S, 1-(2-((2-Chlorobenzyl)thio)ethyl)-5-oxopyrrolidine-3-carboxylic acid contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 313.80 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
CATO manufactures 1-(2-((2-Chlorobenzyl)thio)ethyl)-5-oxopyrrolidine-3-carboxylic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
