66254-56-6 JB295061N4 1-Amino-2-methylpropylphosphonic acid, (R)- UNII-JB295061N4 Phosphonic acid, ((1R)-1-amino-2-methylpropyl)- Phosphonic acid, (1-amino-2-methylpropyl)-, (R)- (1R)-(+)-(1-Amino-2-methylpropyl)phosphonic acid (R)-alpha-Aminoisobutylphosphonic acid J550.870C (CAS 66254-56-6), molecular formula C4H12NO3P and molecular weight 153.12 g/mol, is a CATO reference standard with documented purity and traceability.
66254-56-6 JB295061N4 1-Amino-2-methylpropylphosphonic acid, (R)- UNII-JB295061N4 Phosphonic acid, ((1R)-1-amino-2-methylpropyl)- Phosphonic acid, (1-amino-2-methylpropyl)-, (R)- (1R)-(+)-(1-Amino-2-methylpropyl)phosphonic acid (R)-alpha-Aminoisobutylphosphonic acid J550.870C (C4H12NO3P) contains an amide group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 66254-56-6 JB295061N4 1-Amino-2-methylpropylphosphonic acid, (R)- UNII-JB295061N4 Phosphonic acid, ((1R)-1-amino-2-methylpropyl)- Phosphonic acid, (1-amino-2-methylpropyl)-, (R)- (1R)-(+)-(1-Amino-2-methylpropyl)phosphonic acid (R)-alpha-Aminoisobutylphosphonic acid J550.870C 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.
