Chemical Structure
Description
CATO supplies propionic acid (CAS 79-09-4), a certified reference material (molecular formula C3H6O2, MW 74.08 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, propionic acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 74.08 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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), propionic acid 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.
