Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 248.34 g/mol gives tert-Butyl 2-(cyclopentylsulfonyl)acetate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies tert-Butyl 2-(cyclopentylsulfonyl)acetate (CAS 1504589-15-4), a certified reference material (molecular formula C11H20O4S, MW 248.34 g/mol) for analytical method development and quality control.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, tert-Butyl 2-(cyclopentylsulfonyl)acetate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 248.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), tert-Butyl 2-(cyclopentylsulfonyl)acetate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
