Description
CATO manufactures 2-(O-tolyloxy)benzaldehyde 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.
2-(O-tolyloxy)benzaldehyde (CAS 67698-66-2), molecular formula C14H12O2 and molecular weight 212.24 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 2-(O-tolyloxy)benzaldehyde is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 212.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
