Chemical Structure
Description
As a certified reference material (CRM), 5-Aminobenzene-1,3-diol 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.
5-Aminobenzene-1,3-diol Hydrochloride (CAS 6318-56-5) is a high-purity analytical reference standard with the molecular formula C6H7NO2HCl and a molecular weight of 161.59 g/mol.
5-Aminobenzene-1,3-diol Hydrochloride (C6H7NO2HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
