Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 218.12 g/mol gives 4-Chloro-3,3-dimethylindolinehydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Chloro-3,3-dimethylindolinehydrochloride (CAS 1376321-39-9) is a high-purity analytical reference standard with the molecular formula C10H12ClNHCl and a molecular weight of 218.12 g/mol.
Based on its molecular formula C10H12ClNHCl, 4-Chloro-3,3-dimethylindolinehydrochloride contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 218.12 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
As a certified reference material (CRM), 4-Chloro-3,3-dimethylindolinehydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
