2-(2,2-Dimethylpropanamido)-3-methylbutanoic acid CAS 90891-71-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(2,2-Dimethylpropanamido)-3-methylbutanoic acid.

2-(2,2-Dimethylpropanamido)-3-methylbutanoic acid (CAS 90891-71-7) is a high-purity analytical reference standard with the molecular formula C10H19NO3 and a molecular weight of 201.26 g/mol.

2-(2,2-Dimethylpropanamido)-3-methylbutanoic acid (C10H19NO3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
