(S)-7-Amino-1,2,3-trimethoxy-10-(methylthio)-6,7-dihydrobenzo[A]heptalen-9(5H)-one HCl Salt CAS 16665-61-5

Description

Compared with other compounds in its class, the molecular weight of 409.92 g/mol gives (S)-7-Amino-1,2,3-trimethoxy-10-(methylthio)-6,7-dihydrobenzo[A]heptalen-9(5H)-one HCl Salt distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(S)-7-Amino-1,2,3-trimethoxy-10-(methylthio)-6,7-dihydrobenzo[A]heptalen-9(5H)-one HCl Salt (CAS 16665-61-5) is a high-purity analytical reference standard with the molecular formula C20H23NO4SHCl and a molecular weight of 409.92 g/mol.

The molecular framework of (S)-7-Amino-1,2,3-trimethoxy-10-(methylthio)-6,7-dihydrobenzo[A]heptalen-9(5H)-one HCl Salt (C20H23NO4SHCl) is characterized by a flavonoid core, an amide group, a sulfone 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.

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.
