18:1 dimethylacetal CAS 15677-71-1

Description

Compared with other compounds in its class, the molecular weight of 312.53 g/mol gives 18:1 dimethylacetal distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

18:1 dimethylacetal (CAS 15677-71-1), molecular formula C20H40O2 and molecular weight 312.53 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 18:1 dimethylacetal is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 312.53 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), 18:1 dimethylacetal 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.
