Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-[(tert-Butoxy)carbonyl]bicyclo[1.1.1]pentane-1-carboxylic acid (CAS 1638765-30-6), molecular formula C11H16O4 and molecular weight 212.24 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-[(tert-Butoxy)carbonyl]bicyclo[1.1.1]pentane-1-carboxylic acid (C11H16O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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).
As a certified reference material (CRM), 3-[(tert-Butoxy)carbonyl]bicyclo[1.1.1]pentane-1-carboxylic acid 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.
