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 tert-butyl 3-(5-acetamidoisothiazol-3-yl)pyrrolidine-1-carboxylate.
tert-butyl 3-(5-acetamidoisothiazol-3-yl)pyrrolidine-1-carboxylate (CAS 2007920-23-0), molecular formula C14H21N3O3S and molecular weight 311.40 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, tert-butyl 3-(5-acetamidoisothiazol-3-yl)pyrrolidine-1-carboxylate (C14H21N3O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 311.40 g/mol, it falls into the moderately-high-molecular-weight range. 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), tert-butyl 3-(5-acetamidoisothiazol-3-yl)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.
