3-Chloro-5-phenyl-4-(propan-2-yl)-4h-1,2,4-triazole CAS 1087792-43-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Chloro-5-phenyl-4-(propan-2-yl)-4h-1,2,4-triazole.

3-Chloro-5-phenyl-4-(propan-2-yl)-4h-1,2,4-triazole (CAS 1087792-43-5) is a high-purity analytical reference standard with the molecular formula C11H12ClN3 and a molecular weight of 221.69 g/mol.

Structurally, 3-Chloro-5-phenyl-4-(propan-2-yl)-4h-1,2,4-triazole (C11H12ClN3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine 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 221.69 g/mol, it falls into the medium-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.
