Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1159977-01-1 2-Methyl-benzoic Acid (4-Methoxy-6-(o-acetyl-methyl)-5-methyl-3-pyridinyl)methyl Ester 6-Acetoxymethyl-4-methoxy-5-methyl-3-pyridylmethanol o-Toluate o-Toluic Acid [4-Methoxy-6-(o-acetyl-methyl)-5-methyl-3-pyridinyl]methyl Ester.
CATO supplies 1159977-01-1 2-Methyl-benzoic Acid (4-Methoxy-6-(o-acetyl-methyl)-5-methyl-3-pyridinyl)methyl Ester 6-Acetoxymethyl-4-methoxy-5-methyl-3-pyridylmethanol o-Toluate o-Toluic Acid [4-Methoxy-6-(o-acetyl-methyl)-5-methyl-3-pyridinyl]methyl Ester (CAS 1159977-01-1), a certified reference material (molecular formula C19H21NO5, MW 343.37 g/mol) for analytical method development and quality control.
The molecular framework of 1159977-01-1 2-Methyl-benzoic Acid (4-Methoxy-6-(o-acetyl-methyl)-5-methyl-3-pyridinyl)methyl Ester 6-Acetoxymethyl-4-methoxy-5-methyl-3-pyridylmethanol o-Toluate o-Toluic Acid [4-Methoxy-6-(o-acetyl-methyl)-5-methyl-3-pyridinyl]methyl Ester (C19H21NO5) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
