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 (Z)-2-(2-Oxoindolin-3-ylidene)acetic acid.
CATO supplies (Z)-2-(2-Oxoindolin-3-ylidene)acetic acid (CAS 61854-73-7), a certified reference material (molecular formula C10H7NO3, MW 189.17 g/mol) for analytical method development and quality control.
The molecular framework of (Z)-2-(2-Oxoindolin-3-ylidene)acetic acid (C10H7NO3) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 (Z)-2-(2-Oxoindolin-3-ylidene)acetic acid 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.
