Chemical Structure
Description
The occurrence of 2-Amino-5-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.
CATO supplies 2-Amino-5-methoxybenzoic acid hydrochloride (CAS 1882-70-8), a certified reference material (molecular formula C8H9NO3HCl, MW 203.62 g/mol) for analytical method development and quality control.
Based on its molecular formula C8H9NO3HCl, 2-Amino-5-methoxybenzoic acid hydrochloride contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 203.62 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 2-Amino-5-methoxybenzoic acid hydrochloride 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.
