Benzyl methyl-L-alloisoleucinate 4-methylbenzenesulfonate CAS 201544-39-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Benzyl methyl-L-alloisoleucinate 4-methylbenzenesulfonate.

Benzyl methyl-L-alloisoleucinate 4-methylbenzenesulfonate (CAS 201544-39-0) is a high-purity analytical reference standard with the molecular formula C14H21NO2C7H8O3S and a molecular weight of 407.52 g/mol.

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Benzyl methyl-L-alloisoleucinate 4-methylbenzenesulfonate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 407.52 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
