9,10-Dihydro-1-benzo[a]pyrene-7(8H)-one Oxime CAS 88909-82-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 9,10-Dihydro-1-benzo[a]pyrene-7(8H)-one Oxime.

9,10-Dihydro-1-benzo[a]pyrene-7(8H)-one Oxime (CAS 88909-82-4), molecular formula C20H15NO and molecular weight 285.34 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 9,10-Dihydro-1-benzo[a]pyrene-7(8H)-one Oxime is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 285.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), 9,10-Dihydro-1-benzo[a]pyrene-7(8H)-one Oxime 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.
