(S)-tert-Butyl 2-(5-(4-((trimethylsilyl)ethynyl)phenyl)-1H-imidazol-2-yl)pyrrolidine-1-carboxylate CAS 1228968-40-8 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-(5-(4-((trimethylsilyl)ethynyl)phenyl)-1H-imidazol-2-yl)pyrrolidine-1-carboxylate.

(S)-tert-Butyl 2-(5-(4-((trimethylsilyl)ethynyl)phenyl)-1H-imidazol-2-yl)pyrrolidine-1-carboxylate (CAS 1228968-40-8) is a high-purity analytical reference standard with the molecular formula C23H31N3O2Si and a molecular weight of 409.60 g/mol.

The molecular framework of (S)-tert-Butyl 2-(5-(4-((trimethylsilyl)ethynyl)phenyl)-1H-imidazol-2-yl)pyrrolidine-1-carboxylate (C23H31N3O2Si) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

As a certified reference material (CRM), (S)-tert-Butyl 2-(5-(4-((trimethylsilyl)ethynyl)phenyl)-1H-imidazol-2-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.
