2,5-Bis(bromomethyl)cyclohexa-2,5-diene-1,4-dione CAS 120475-64-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,5-Bis(bromomethyl)cyclohexa-2,5-diene-1,4-dione.

2,5-Bis(bromomethyl)cyclohexa-2,5-diene-1,4-dione (CAS 120475-64-1) is a high-purity analytical reference standard with the molecular formula C8H6Br2O2 and a molecular weight of 293.94 g/mol.

Structurally, 2,5-Bis(bromomethyl)cyclohexa-2,5-diene-1,4-dione (C8H6Br2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 293.94 g/mol, it falls into the medium-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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
