Chemical Structure

4-Chlorobenzoic acid-phenyl-<SUP>13</SUP>C<SUB>6</SUB> CAS 1173019-28-7 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.

4-Chlorobenzoic acid-phenyl-<SUP>13</SUP>C<SUB>6</SUB> (CAS 1173019-28-7), molecular formula C[13C]6H5ClO2 and molecular weight 162.52 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 4-Chlorobenzoic acid-phenyl-<SUP>13</SUP>C<SUB>6</SUB> is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 162.52 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
