Description
CATO manufactures 5-Amino-4-hydroxyisophthalic acid hydrochloride 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.
5-Amino-4-hydroxyisophthalic acid hydrochloride (CAS 628262-26-0) is a high-purity analytical reference standard with the molecular formula C8H7NO5HCl and a molecular weight of 233.60 g/mol.
5-Amino-4-hydroxyisophthalic acid hydrochloride (C8H7NO5HCl) contains a nitrogen-containing heterocyclic scaffold, an amide 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. 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.
