2-Acetoxybenzoic-3,4,5,6-d4 acid Chemical Properties,Uses,Production

Description

Aspirin-d4 is intended for use as an internal standard for the quantification of aspirin by GC- or LC-MS. Aspirin is a non-selective, irreversible COX inhibitor. The IC50 values for ovine COX-1 and -2 are 0.75 and 1.25 mM, respectively. Aspirin acetylates COX-1 at Ser530 and COX-2 at Ser516 resulting in irreversible enzyme inhibition.

Chemical Properties

2-ACETOXYBENZOIC-3,4,5,6-D4 ACID is Off-White Solid

Uses

Analgesic; antipyretic; anti-inflammatory; antithrombotic

Uses

Labeled Aspirin, intended for use as an internal standard for the quantification of Aspirin by GC- or LC-mass spectrometry.
