Methyl 4-{[(5-chloro-2-hydroxyphenyl)methylidene]-amino}-3-fluorobenzoate CAS 1296225-20-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl 4-{[(5-chloro-2-hydroxyphenyl)methylidene]-amino}-3-fluorobenzoate.

Methyl 4-{[(5-chloro-2-hydroxyphenyl)methylidene]-amino}-3-fluorobenzoate (CAS 1296225-20-1), molecular formula C15H11ClFNO3 and molecular weight 307.70 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, Methyl 4-{[(5-chloro-2-hydroxyphenyl)methylidene]-amino}-3-fluorobenzoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 307.70 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.

CATO manufactures Methyl 4-{[(5-chloro-2-hydroxyphenyl)methylidene]-amino}-3-fluorobenzoate 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.
