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 2-(4-methylphenyl)-3-sulfanylidene-1,4,8-triazaspiro[4.5]dec-1-ene-8-carboxylate.
tert-Butyl 2-(4-methylphenyl)-3-sulfanylidene-1,4,8-triazaspiro[4.5]dec-1-ene-8-carboxylate (CAS 892290-03-8), molecular formula C19H25N3O2S and molecular weight 359.49 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, tert-Butyl 2-(4-methylphenyl)-3-sulfanylidene-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 359.49 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).
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), tert-Butyl 2-(4-methylphenyl)-3-sulfanylidene-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.
