Pyrene-2,7-dicarbaldehyde CAS 43213-20-3 chemical structure

Description

CATO supplies Pyrene-2,7-dicarbaldehyde (CAS 43213-20-3), a certified reference material (molecular formula C18H10O2, MW 258.27 g/mol) for analytical method development and quality control.

Pyrene-2,7-dicarbaldehyde (C18H10O2) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), Pyrene-2,7-dicarbaldehyde 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.
