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 6-(Trimethylsilyl)-2,3-dihydroindolizine-5(1H)-thione.
CATO supplies 6-(Trimethylsilyl)-2,3-dihydroindolizine-5(1H)-thione (CAS 113885-17-9), a certified reference material (molecular formula C11H17NSSi, MW 223.41 g/mol) for analytical method development and quality control.
Structurally, 6-(Trimethylsilyl)-2,3-dihydroindolizine-5(1H)-thione (C11H17NSSi) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 223.41 g/mol, it falls into the medium-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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
