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-5,6,7,8-tetrahydronaphthalene-2-carbonitrile.
1,3-Dibromo-5,6,7,8-tetrahydronaphthalene-2-carbonitrile (CAS 2768872-19-9) is a high-purity analytical reference standard with the molecular formula C11H9Br2N and a molecular weight of 315.00 g/mol.
Structurally, 1,3-Dibromo-5,6,7,8-tetrahydronaphthalene-2-carbonitrile (C11H9Br2N) 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 315.00 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
