2-Hydroxyacetophenone D7 CAS 1189865-36-8 chemical structure

Description

As a certified reference material (CRM), 2-Hydroxyacetophenone D7 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.

2-Hydroxyacetophenone D7 (CAS 1189865-36-8), molecular formula C8HD7O2 and molecular weight 143.19 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 2-Hydroxyacetophenone D7 is typically pale yellow to yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 143.19 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).

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.
