Chemical Structure

Chrysene-d12 CAS 1719-03-5 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies Chrysene-d12 (CAS 1719-03-5), a certified reference material (molecular formula C18D12, MW 240.36 g/mol) for analytical method development and quality control.

Structurally, Chrysene-d12 (C18D12) contains deuterium isotope labeling, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 19.0, corresponding to approximately 19 ring(s) or double-bond equivalent(s). With a molecular weight of 240.36 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
