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 Methyl (S)-3-(4-aminophenyl)-2-(2,6-dichlorobenzamido)propanoate.
Methyl (S)-3-(4-aminophenyl)-2-(2,6-dichlorobenzamido)propanoate (CAS 554419-04-4) is a high-purity analytical reference standard with the molecular formula C17H16Cl2N2O3 and a molecular weight of 367.23 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Methyl (S)-3-(4-aminophenyl)-2-(2,6-dichlorobenzamido)propanoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 367.23 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.
