Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Hydroxy-4-methoxybenzoic Acid Methyl Ester 4-Methoxysalicylic Acid Methyl Ester 5446-02-6 M1797 Methyl 2-Hydroxy-4-methoxybenzoate Methyl 2-Hydroxy-p-anisate Methyl 4-Methoxysalicylate.

2-Hydroxy-4-methoxybenzoic Acid Methyl Ester 4-Methoxysalicylic Acid Methyl Ester 5446-02-6 M1797 Methyl 2-Hydroxy-4-methoxybenzoate Methyl 2-Hydroxy-p-anisate Methyl 4-Methoxysalicylate (CAS 5446-02-6) is a high-purity analytical reference standard with the molecular formula C9H16O4 and a molecular weight of 188.22 g/mol.

The molecular framework of 2-Hydroxy-4-methoxybenzoic Acid Methyl Ester 4-Methoxysalicylic Acid Methyl Ester 5446-02-6 M1797 Methyl 2-Hydroxy-4-methoxybenzoate Methyl 2-Hydroxy-p-anisate Methyl 4-Methoxysalicylate (C9H16O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.

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.
