Chemical Structure
Description
As a certified reference material (CRM), Isobutyl Butyrate 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.
Isobutyl Butyrate (CAS 539-90-2), molecular formula C8H16O2 and molecular weight 144.21 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Isobutyl Butyrate is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 144.21 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.
