Chemical Structure

(S)-5-tert-Butyl 6-methyl 2-iodo-3-((2-(trimethylsilyl)ethoxy)methyl)-6,7-dihydro-3H-imidazo[4,5-c]pyridine-5,6(4H)-dicarboxylate CAS 2243987-13-3 chemical structure

Description

The occurrence of (S)-5-tert-Butyl 6-methyl 2-iodo-3-((2-(trimethylsilyl)ethoxy)methyl)-6,7-dihydro-3H-imidazo[4,5-c]pyridine-5,6(4H)-dicarboxylate is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(S)-5-tert-Butyl 6-methyl 2-iodo-3-((2-(trimethylsilyl)ethoxy)methyl)-6,7-dihydro-3H-imidazo[4,5-c]pyridine-5,6(4H)-dicarboxylate (CAS 2243987-13-3), molecular formula C19H32IN3O5Si and molecular weight 537.46 g/mol, is a CATO reference standard with documented purity and traceability.

(S)-5-tert-Butyl 6-methyl 2-iodo-3-((2-(trimethylsilyl)ethoxy)methyl)-6,7-dihydro-3H-imidazo[4,5-c]pyridine-5,6(4H)-dicarboxylate (C19H32IN3O5Si) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), (S)-5-tert-Butyl 6-methyl 2-iodo-3-((2-(trimethylsilyl)ethoxy)methyl)-6,7-dihydro-3H-imidazo[4,5-c]pyridine-5,6(4H)-dicarboxylate 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.
