methyl bicyclo[2.2.1]heptane-2-carboxylate CAS 35520-81-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including methyl bicyclo[2.2.1]heptane-2-carboxylate.

methyl bicyclo[2.2.1]heptane-2-carboxylate (CAS 35520-81-1) is a high-purity analytical reference standard with the molecular formula C28H22BrNOS and a molecular weight of 500.45 g/mol.

Structurally, methyl bicyclo[2.2.1]heptane-2-carboxylate (C28H22BrNOS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 18.0, corresponding to approximately 18 ring(s) or double-bond equivalent(s). With a molecular weight of 500.45 g/mol, it falls into the moderately-high-molecular-weight range. 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).

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.
