methyl 5-bromobicyclo[3.1.1]heptane-1-carboxylate CAS 91239-76-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including methyl 5-bromobicyclo[3.1.1]heptane-1-carboxylate.

methyl 5-bromobicyclo[3.1.1]heptane-1-carboxylate (CAS 91239-76-8), molecular formula C9H13BrO2 and molecular weight 233.10 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, methyl 5-bromobicyclo[3.1.1]heptane-1-carboxylate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 233.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
