Description
CATO manufactures 3-Chloro-5-ethoxy-4-[(4-methylbenzyl)oxy]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.
3-Chloro-5-ethoxy-4-[(4-methylbenzyl)oxy]benzaldehyde (CAS 634593-07-0) is a high-purity analytical reference standard with the molecular formula C17H17ClO3 and a molecular weight of 304.77 g/mol.
Owing to a steroid core, a hydroxyl group, an ether linkage, chlorine substitution, 3-Chloro-5-ethoxy-4-[(4-methylbenzyl)oxy]benzaldehyde is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 304.77 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
