1,1-Dichloro-2,2-dimethylpropane CAS 29559-54-4 chemical structure

Description

As a certified reference material (CRM), 1,1-Dichloro-2,2-dimethylpropane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

1,1-Dichloro-2,2-dimethylpropane (CAS 29559-54-4), molecular formula C5H10Cl2 and molecular weight 141.04 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to chlorine substitution, 1,1-Dichloro-2,2-dimethylpropane is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 141.04 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.

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.
