1,3,3-trimethyl-2-oxabicyclo[2.1.1]hexane-4-carboxylic acid CAS 2219371-57-8

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 1,3,3-trimethyl-2-oxabicyclo[2.1.1]hexane-4-carboxylic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 170.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

1,3,3-trimethyl-2-oxabicyclo[2.1.1]hexane-4-carboxylic acid (CAS 2219371-57-8), molecular formula C9H14O3 and molecular weight 170.21 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), 1,3,3-trimethyl-2-oxabicyclo[2.1.1]hexane-4-carboxylic 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.
