Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 178.61 g/mol gives 1-Chloro-7-naphthol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-Chloro-7-naphthol (CAS 29921-50-4), molecular formula C10H7ClO and molecular weight 178.61 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-Chloro-7-naphthol (C10H7ClO) is characterized by a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 1-Chloro-7-naphthol 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.
