Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Calcium naphthalen-1-yl hydrogen phosphate (CAS 4588-86-7), a certified reference material (molecular formula C10H8O4PCa, MW 263.22 g/mol) for analytical method development and quality control.
Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Calcium naphthalen-1-yl hydrogen phosphate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 263.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures Calcium naphthalen-1-yl hydrogen phosphate 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.
