Chemical Structure
Description
As a certified reference material (CRM), 3-Chloro-3-ethylpentane 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.
3-Chloro-3-ethylpentane (CAS 994-25-2), molecular formula C7H15Cl and molecular weight 134.65 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to chlorine substitution, 3-Chloro-3-ethylpentane is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 134.65 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
