Chemical Structure

Naftalofos CAS 1491-41-4 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

Naftalofos (CAS 1491-41-4), molecular formula C16H16NO6P and molecular weight 349.28 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, Naftalofos is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 349.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO manufactures Naftalofos 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.
