Chemical Structure
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.
2,2,3-Trimethylcyclopent-3-ene-1-carboxaldehyde (CAS 33843-21-9) is a high-purity analytical reference standard with the molecular formula C9H14O and a molecular weight of 138.21 g/mol.
The molecular framework of 2,2,3-Trimethylcyclopent-3-ene-1-carboxaldehyde (C9H14O) is characterized by a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
CATO manufactures 2,2,3-Trimethylcyclopent-3-ene-1-carboxaldehyde 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.
