Chemical Structure
Description
The occurrence of 4-Guanidino-2-methoxybenzoic Acid Hydrochloride is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Guanidino-2-methoxybenzoic Acid Hydrochloride (CAS 1028486-08-9), molecular formula C9H11N3O3HCl and molecular weight 245.66 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Guanidino-2-methoxybenzoic Acid Hydrochloride (C9H11N3O3HCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 4-Guanidino-2-methoxybenzoic 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.
