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 5-(3-Chlorophenyl)-1-(3,4-dichlorophenyl)-1H-tetrazole.
5-(3-Chlorophenyl)-1-(3,4-dichlorophenyl)-1H-tetrazole (CAS 338411-30-6) is a high-purity analytical reference standard with the molecular formula C13H7Cl3N4 and a molecular weight of 325.58 g/mol.
Structurally, 5-(3-Chlorophenyl)-1-(3,4-dichlorophenyl)-1H-tetrazole (C13H7Cl3N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 325.58 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.
