Chemical Structure
Description
The occurrence of 1-(Chloromethyl)-4-methylnaphthalene is closely related to chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1-(Chloromethyl)-4-methylnaphthalene (CAS 5261-50-7), a certified reference material (molecular formula C12H11Cl, MW 190.67 g/mol) for analytical method development and quality control.
1-(Chloromethyl)-4-methylnaphthalene (C12H11Cl) contains chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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 1-(Chloromethyl)-4-methylnaphthalene 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.
