2,2'-methylenebis[(4 <I> R </I> ,5 <I> S </I>)-4,5-diphenyl-2-oxazoline] CAS 139021-82-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,2'-methylenebis[(4 <I> R </I> ,5 <I> S </I>)-4,5-diphenyl-2-oxazoline].

2,2'-methylenebis[(4 <I> R </I> ,5 <I> S </I>)-4,5-diphenyl-2-oxazoline] (CAS 139021-82-2) is a high-purity analytical reference standard with the molecular formula C31H50N2O2 and a molecular weight of 482.74 g/mol.

Based on its molecular formula C31H50N2O2, 2,2'-methylenebis[(4 <I> R </I> ,5 <I> S </I>)-4,5-diphenyl-2-oxazoline] contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 482.74 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 2,2'-methylenebis[(4 <I> R </I> ,5 <I> S </I>)-4,5-diphenyl-2-oxazoline] 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.
