Chemical Structure
Description
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.
1-(Naphthalen-1-ylmethyl)-1H-benzo[d]imidazole-2-carbaldehyde (CAS 537010-28-9), molecular formula C19H14N2O and molecular weight 286.33 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(Naphthalen-1-ylmethyl)-1H-benzo[d]imidazole-2-carbaldehyde (C19H14N2O) is characterized by a steroid core, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
