Chemical Structure

2,4-Dichlorophenyldiazo-1,5-naphthalene disulfonate hydrate CAS 123333-91-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 495.43 g/mol gives 2,4-Dichlorophenyldiazo-1,5-naphthalene disulfonate hydrate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2,4-Dichlorophenyldiazo-1,5-naphthalene disulfonate hydrate (CAS 123333-91-5), a certified reference material (molecular formula C10H17O6S2C6H9Cl2N2H2O, MW 495.43 g/mol) for analytical method development and quality control.

2,4-Dichlorophenyldiazo-1,5-naphthalene disulfonate hydrate (C10H17O6S2C6H9Cl2N2H2O) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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 2,4-Dichlorophenyldiazo-1,5-naphthalene disulfonate hydrate 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.
