Chemical Structure
Description
4-Methyl-1,2-dihydronaphthalene (CAS 4373-13-1), molecular formula C11H12 and molecular weight 144.21 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an aromatic ring system, 4-Methyl-1,2-dihydronaphthalene is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 144.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 4-Methyl-1,2-dihydronaphthalene 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.
