Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 133.63 g/mol gives 4-Chlorotoluene-d7 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Chlorotoluene-d7 (CAS 84344-06-9), molecular formula C7D7Cl and molecular weight 133.63 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to deuterium isotope labeling, chlorine substitution, an aromatic ring system, 4-Chlorotoluene-d7 is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 133.63 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-Chlorotoluene-d7 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.
