Chemical Structure

Pentyl isobutyrate CAS 2445-72-9 chemical structure

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

Pentyl isobutyrate (CAS 2445-72-9), molecular formula C9H18O2 and molecular weight 158.24 g/mol, is a CATO reference standard with documented purity and traceability.

Pentyl isobutyrate (C9H18O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

As a certified reference material (CRM), Pentyl isobutyrate 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.
