Chemical Structure
Description
CATO supplies 4-(4-Hydroxy-1-butynl)-a,a-di-(methyl-D3)-benzeneacetic Acid Methyl Ester (CAS 1020719-49-6), a certified reference material (molecular formula C15H18O3, MW 246.30 g/mol) for analytical method development and quality control.
4-(4-Hydroxy-1-butynl)-a,a-di-(methyl-D3)-benzeneacetic Acid Methyl Ester (C15H18O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 4-(4-Hydroxy-1-butynl)-a,a-di-(methyl-D3)-benzeneacetic Acid Methyl Ester 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.
