Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 189.08 g/mol gives 2,4-Dichloro-1-isopropylbenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,4-Dichloro-1-isopropylbenzene (CAS 65432-03-3) is a high-purity analytical reference standard with the molecular formula C9H10Cl2 and a molecular weight of 189.08 g/mol.
2,4-Dichloro-1-isopropylbenzene (C9H10Cl2) contains chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures 2,4-Dichloro-1-isopropylbenzene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
