Description
2-Naphthalenecarboxamide, 7-bromo-N-(2-methoxyphenyl)-3-(phosphonooxy)-, disodium salt hydrate 207569-04-8 Naphthol AS-BI phosphate disodium salt hydrate (CAS 207569-04-8) is a high-purity analytical reference standard with the molecular formula C18H29BrNO6PNaH2O and a molecular weight of 507.31 g/mol.
2-Naphthalenecarboxamide, 7-bromo-N-(2-methoxyphenyl)-3-(phosphonooxy)-, disodium salt hydrate 207569-04-8 Naphthol AS-BI phosphate disodium salt hydrate (C18H29BrNO6PNaH2O) contains a salt form, an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-Naphthalenecarboxamide, 7-bromo-N-(2-methoxyphenyl)-3-(phosphonooxy)-, disodium salt hydrate 207569-04-8 Naphthol AS-BI phosphate disodium salt hydrate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
