Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (3R,4S,5S)-tert-butyl 4-((S)-2-amino-N,3-dimethylbutanamido)-3-methoxy-5-methylheptanoate.
CATO supplies (3R,4S,5S)-tert-butyl 4-((S)-2-amino-N,3-dimethylbutanamido)-3-methoxy-5-methylheptanoate (CAS 177423-00-6), a certified reference material (molecular formula C19H38N2O4, MW 358.52 g/mol) for analytical method development and quality control.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, (3R,4S,5S)-tert-butyl 4-((S)-2-amino-N,3-dimethylbutanamido)-3-methoxy-5-methylheptanoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 358.52 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
