Chemical Structure
Description
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.
1-[(5-chloro-1-methyl-1h-imidazol-2-yl)methyl]-1h-indole-2-carboxylic acid (CAS 1094451-89-4), molecular formula C14H12ClN3O2 and molecular weight 289.72 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-[(5-chloro-1-methyl-1h-imidazol-2-yl)methyl]-1h-indole-2-carboxylic acid (C14H12ClN3O2) 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 289.72 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
