Description
CATO manufactures 221682-86-6 3-oxo-2-(4-hydroxy-2-(z)-pentenyl)cyclopentane-1-acetic 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.
CATO supplies 221682-86-6 3-oxo-2-(4-hydroxy-2-(z)-pentenyl)cyclopentane-1-acetic acid (CAS 221682-86-6), a certified reference material (molecular formula C12H18O4, MW 226.27 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 221682-86-6 3-oxo-2-(4-hydroxy-2-(z)-pentenyl)cyclopentane-1-acetic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 226.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
