Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-tert-Butyl (2-ethynylpyrrolidin-1-yl)sulfonylcarbamate.
(S)-tert-Butyl (2-ethynylpyrrolidin-1-yl)sulfonylcarbamate (CAS 1108658-64-5) is a high-purity analytical reference standard with the molecular formula C11H18N2O4S and a molecular weight of 274.34 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, (S)-tert-Butyl (2-ethynylpyrrolidin-1-yl)sulfonylcarbamate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 274.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
