Chemical Structure
Description
The occurrence of rel-Methyl (1R,3S)-3-formylcyclopentane-1-carboxylate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
rel-Methyl (1R,3S)-3-formylcyclopentane-1-carboxylate (CAS 65553-68-6), molecular formula C8H12O3 and molecular weight 156.18 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of rel-Methyl (1R,3S)-3-formylcyclopentane-1-carboxylate (C8H12O3) is characterized by a carboxylic acid group, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
