Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Benzyl 8-bromo-6-chloro-3,4-dihydroisoquinoline-2(1H)-carboxylate.
Benzyl 8-bromo-6-chloro-3,4-dihydroisoquinoline-2(1H)-carboxylate (CAS 2680664-07-5), molecular formula C17H15BrClNO2 and molecular weight 380.66 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Benzyl 8-bromo-6-chloro-3,4-dihydroisoquinoline-2(1H)-carboxylate (C17H15BrClNO2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
