Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
tert-Butyl 5-formyl-3,4-dihydroisoquinoline-2(1H)-carboxylate (CAS 441065-33-4), molecular formula C15H19NO3 and molecular weight 261.32 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of tert-Butyl 5-formyl-3,4-dihydroisoquinoline-2(1H)-carboxylate (C15H19NO3) is characterized by a nitrogen-containing heterocyclic scaffold, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), tert-Butyl 5-formyl-3,4-dihydroisoquinoline-2(1H)-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.
