Description
As a certified reference material (CRM), (S)-tert-Butyl 3-((6-ethoxy-2-(methylthio)pyrimidin-4-yl)amino)pyrrolidine-1-carboxylate 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.
(S)-tert-Butyl 3-((6-ethoxy-2-(methylthio)pyrimidin-4-yl)amino)pyrrolidine-1-carboxylate (CAS 1354020-92-0), molecular formula C16H26N4O3S and molecular weight 354.47 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, (S)-tert-Butyl 3-((6-ethoxy-2-(methylthio)pyrimidin-4-yl)amino)pyrrolidine-1-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 354.47 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
