Chemical Structure
Description
The occurrence of 3-Isopropyl-5-(methylthio)benzaldehyde is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Isopropyl-5-(methylthio)benzaldehyde (CAS 1289031-77-1), molecular formula C11H14OS and molecular weight 194.29 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system, 3-Isopropyl-5-(methylthio)benzaldehyde is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 194.29 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3-Isopropyl-5-(methylthio)benzaldehyde meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
