Description

Compared with other compounds in its class, the molecular weight of 267.28 g/mol gives 1-[3-(4-Methoxyphenyl)-2,1-benzoxazol-5-yl]ethan-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1-[3-(4-Methoxyphenyl)-2,1-benzoxazol-5-yl]ethan-1-one (CAS 439094-07-2), a certified reference material (molecular formula C16H13NO3, MW 267.28 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 1-[3-(4-Methoxyphenyl)-2,1-benzoxazol-5-yl]ethan-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 267.28 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), 1-[3-(4-Methoxyphenyl)-2,1-benzoxazol-5-yl]ethan-1-one 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.
