Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(S)-[2-[[(tert-Butoxy)carbonyl]amino]-4-methylpentyl]carbamicacid benzylester (CAS 115654-39-2) is a high-purity analytical reference standard with the molecular formula C19H30N2O4 and a molecular weight of 350.45 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, (S)-[2-[[(tert-Butoxy)carbonyl]amino]-4-methylpentyl]carbamicacid benzylester is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 350.45 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), (S)-[2-[[(tert-Butoxy)carbonyl]amino]-4-methylpentyl]carbamicacid benzylester 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.
