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 1-methyl-1H-indole-3-carbaldehyde oxime.
1-methyl-1H-indole-3-carbaldehyde oxime (CAS 40747-07-7), molecular formula C10H10N2O and molecular weight 174.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-methyl-1H-indole-3-carbaldehyde oxime (C10H10N2O) is characterized by a nitrogen-containing heterocyclic scaffold, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 1-methyl-1H-indole-3-carbaldehyde oxime 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.
