Chemical Structure

N-Me-Leu-OBzl · p-tosylate CAS 42807-66-9 chemical structure

Description

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.

N-Me-Leu-OBzl · p-tosylate (CAS 42807-66-9), molecular formula C14H21NO2C7H8O3S and molecular weight 407.52 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, N-Me-Leu-OBzl · p-tosylate 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO manufactures N-Me-Leu-OBzl · p-tosylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
