Chemical Structure
Description
1-Chloro-5-methylhexane (CAS 33240-56-1), molecular formula C7H15Cl and molecular weight 134.65 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C7H15Cl, 1-Chloro-5-methylhexane contains chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 134.65 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
As a certified reference material (CRM), 1-Chloro-5-methylhexane 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.
