Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-(Aminomethyl)benzene-1,2-diol hydrochloride (CAS 1194-90-7), molecular formula C7H9NO2HCl and molecular weight 175.61 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(Aminomethyl)benzene-1,2-diol hydrochloride (C7H9NO2HCl) is characterized by an amide group, a carboxylic acid 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), 3-(Aminomethyl)benzene-1,2-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.
