Chemical Structure
Description
Butyric propionic anhydride (CAS 874525-73-2), molecular formula C7H12O3 and molecular weight 144.17 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Butyric propionic anhydride (C7H12O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.
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), Butyric propionic anhydride 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.
