Chemical Structure

Iso-butyl-2-methylbutyrate CAS 2445-67-2 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Iso-butyl-2-methylbutyrate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 158.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

Iso-butyl-2-methylbutyrate (CAS 2445-67-2), molecular formula C9H18O2 and molecular weight 158.24 g/mol, is a CATO reference standard with documented purity and traceability.

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.

As a certified reference material (CRM), Iso-butyl-2-methylbutyrate 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.
