Chemical Structure
Description
CATO supplies Tert-butyl (4-ethynyltetrahydro-2H-pyran-4-yl)carbamate (CAS 287192-92-1), a certified reference material (molecular formula C12H19NO3, MW 225.28 g/mol) for analytical method development and quality control.
The molecular framework of Tert-butyl (4-ethynyltetrahydro-2H-pyran-4-yl)carbamate (C12H19NO3) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 (4-ethynyltetrahydro-2H-pyran-4-yl)carbamate 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.
