Chemical Structure

1,7-Heptanediol-1,3,5,7-<SUP>13</SUP>C<SUB>4</SUB> CAS 2421217-08-3 chemical structure

Description

1,7-Heptanediol-1,3,5,7-<SUP>13</SUP>C<SUB>4</SUB> (CAS 2421217-08-3), molecular formula C3[13C]4H16O2 and molecular weight 136.17 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 1,7-Heptanediol-1,3,5,7-<SUP>13</SUP>C<SUB>4</SUB> is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 136.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.

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.
