Product Overview
1-Chloromethyl naphthalene (CAS 86-52-2), also known as 1-(chloromethyl)naphthalene or 1-naphthylmethyl chloride, is a reactive aromatic halide. It is a white to light yellow crystalline solid, melting near room temperature. As a key alkylating agent and organic intermediate, it is widely used in pharmaceutical synthesis, dye production, resin chemistry and academic research. Manufactured via chloromethylation and purification, it offers ≥95% GC purity, low moisture and stable batch performance. For industrial synthesis and research use only.
Product Features
- High Purity: ≥95.0% (GC), suitable for fine chemical and pharmaceutical intermediate grades.
- High Reactivity: Reactive benzyl chloride moiety for nucleophilic substitution and cross-coupling reactions.
- Good Solubility: Soluble in organic solvents; insoluble in water.
- Thermal Stability: Stable at ambient temperature; decomposes at elevated temperatures.
- Quality Assurance: COA, MSDS and HPLC/GC data available on request.
