Chemical Structure

1459-15-0 Benzene, (1-chloroethyl)-, (R)- CAS 1459-15-0 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.

1459-15-0 Benzene, (1-chloroethyl)-, (R)- (CAS 1459-15-0), molecular formula C8H9Cl and molecular weight 140.61 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to chlorine substitution, an aromatic ring system, 1459-15-0 Benzene, (1-chloroethyl)-, (R)- is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 140.61 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
