Chemical Structure

1,3-Dibromo-6,6-dimethyl-5,6,7,8-tetrahydronaphthalene-2-carbonitrile CAS 2768875-73-4 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 1,3-Dibromo-6,6-dimethyl-5,6,7,8-tetrahydronaphthalene-2-carbonitrile.

CATO supplies 1,3-Dibromo-6,6-dimethyl-5,6,7,8-tetrahydronaphthalene-2-carbonitrile (CAS 2768875-73-4), a certified reference material (molecular formula C13H13Br2N, MW 343.06 g/mol) for analytical method development and quality control.

Structurally, 1,3-Dibromo-6,6-dimethyl-5,6,7,8-tetrahydronaphthalene-2-carbonitrile (C13H13Br2N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 343.06 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.
