Chemical Structure
Description
As a certified reference material (CRM), 2-Ethynyl-1-methoxy-4-methylbenzene 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.
CATO supplies 2-Ethynyl-1-methoxy-4-methylbenzene (CAS 104971-07-5), a certified reference material (molecular formula C10H10O, MW 146.19 g/mol) for analytical method development and quality control.
2-Ethynyl-1-methoxy-4-methylbenzene (C10H10O) contains a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
