Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 244.24 g/mol gives dimethyl naphthalene-2,7-dicarboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
dimethyl naphthalene-2,7-dicarboxylate (CAS 2549-47-5), molecular formula C14H12O4 and molecular weight 244.24 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, dimethyl naphthalene-2,7-dicarboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 244.24 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 dimethyl naphthalene-2,7-dicarboxylate 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.
