Chemical Structure
Description
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.
Tert-butyl 2-phenyl-3-thioxo-1,4,8-triazaspiro[4.5]Dec-1-ene-8-carboxylate (CAS 892289-95-1) is a high-purity analytical reference standard with the molecular formula C18H23N3O2S and a molecular weight of 345.46 g/mol.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Tert-butyl 2-phenyl-3-thioxo-1,4,8-triazaspiro[4.5]Dec-1-ene-8-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 345.46 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
As a certified reference material (CRM), Tert-butyl 2-phenyl-3-thioxo-1,4,8-triazaspiro[4.5]Dec-1-ene-8-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.
