Chemical Structure

Pyrene-4,5,9,10-<SUP>13</SUP>C<SUB>4</SUB> CAS 1173023-76-1 chemical structure

Description

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.

Pyrene-4,5,9,10-<SUP>13</SUP>C<SUB>4</SUB> (CAS 1173023-76-1) is a high-purity analytical reference standard with the molecular formula C12[13C]4H22 and a molecular weight of 218.32 g/mol.

Owing to an organic framework, Pyrene-4,5,9,10-<SUP>13</SUP>C<SUB>4</SUB> is typically white to off-white low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 218.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
