Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 186.21 g/mol gives (1R,3S)-3-(methoxycarbonyl)-2,2-dimethylcyclobutane-1-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (1R,3S)-3-(methoxycarbonyl)-2,2-dimethylcyclobutane-1-carboxylic acid (CAS 1959577-68-4), a certified reference material (molecular formula C9H14O4, MW 186.21 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, (1R,3S)-3-(methoxycarbonyl)-2,2-dimethylcyclobutane-1-carboxylic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 186.21 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).
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.
