Chemical Structure

3,5-Dimethylbenzyl Alcohol CAS 27129-87-9 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.

3,5-Dimethylbenzyl Alcohol (CAS 27129-87-9) is a high-purity analytical reference standard with the molecular formula C9H12O and a molecular weight of 136.19 g/mol.

Owing to a hydroxyl group, an ether linkage, an aromatic ring system, 3,5-Dimethylbenzyl Alcohol is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 136.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), 3,5-Dimethylbenzyl Alcohol 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.
