Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 170.64 g/mol gives 4-Chloro-1-ethoxy-2-methylbenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Chloro-1-ethoxy-2-methylbenzene (CAS 35338-32-0) is a high-purity analytical reference standard with the molecular formula C9H11ClO and a molecular weight of 170.64 g/mol.
4-Chloro-1-ethoxy-2-methylbenzene (C9H11ClO) contains a hydroxyl group, an ether linkage, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 4-Chloro-1-ethoxy-2-methylbenzene 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.
