Chemical Structure
Description
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.
3-Amino-5-hydroxybenzoic Acid Hydrochloride (CAS 14206-69-0), molecular formula C7H7NO3HCl and molecular weight 189.59 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C7H7NO3HCl, 3-Amino-5-hydroxybenzoic Acid Hydrochloride contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 189.59 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), 3-Amino-5-hydroxybenzoic 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.
