Description
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.
1-Octadecyl-5-oxopyrrolidine-3-carboxylic acid (CAS 10054-20-3) is a high-purity analytical reference standard with the molecular formula C11H7ClF3N3 and a molecular weight of 273.64 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution, 1-Octadecyl-5-oxopyrrolidine-3-carboxylic acid is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 273.64 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures 1-Octadecyl-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.
