4-(6-Chloro-1-ethyl-1H-benzo[d]imidazol-2-yl)phenol CAS 1552159-26-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(6-Chloro-1-ethyl-1H-benzo[d]imidazol-2-yl)phenol.

4-(6-Chloro-1-ethyl-1H-benzo[d]imidazol-2-yl)phenol (CAS 1552159-26-8), molecular formula C15H13ClN2O and molecular weight 272.73 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4-(6-Chloro-1-ethyl-1H-benzo[d]imidazol-2-yl)phenol (C15H13ClN2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 272.73 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
