6872-17-9 5-Chloro-1,3,3-trimethyl-2-methyleneindoline 1H-Indole, 5-chloro-2,3-dihydro-1,3,3-trimethyl-2-methylene- EINECS 229-972-6 CAS 6872-17-9 chemical structure

Description

6872-17-9 5-Chloro-1,3,3-trimethyl-2-methyleneindoline 1H-Indole, 5-chloro-2,3-dihydro-1,3,3-trimethyl-2-methylene- EINECS 229-972-6 (CAS 6872-17-9) is a high-purity analytical reference standard with the molecular formula C12H20ClN and a molecular weight of 213.75 g/mol.

Based on its molecular formula C12H20ClN, 6872-17-9 5-Chloro-1,3,3-trimethyl-2-methyleneindoline 1H-Indole, 5-chloro-2,3-dihydro-1,3,3-trimethyl-2-methylene- EINECS 229-972-6 contains a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 213.75 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), 6872-17-9 5-Chloro-1,3,3-trimethyl-2-methyleneindoline 1H-Indole, 5-chloro-2,3-dihydro-1,3,3-trimethyl-2-methylene- EINECS 229-972-6 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.
