Description
CATO manufactures (2-Chlorophenyl)diphenyl-d5-methanol (phenyl-d5) under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
(2-Chlorophenyl)diphenyl-d5-methanol (phenyl-d5) (CAS 1219802-30-8), molecular formula C19H10D5ClO and molecular weight 299.81 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage, chlorine substitution, (2-Chlorophenyl)diphenyl-d5-methanol (phenyl-d5) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 299.81 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
